1. Trustown Non-Contact Forehead and Ear Thermometer – The Cheap Choice

Introduction

Our first 7-best pick is a highly portable, easy to use and fairly accurate infrared thermometer, designed for objects and people of all ages and supporting forehead and ear function.

View on Amazon

At a Glance

  • Suitable for adults, children and babies
  • High precision infrared sensor
  • Multi-mode Thermometer:
    It supports forehead and ear function
    Capable of taking room/object temperature
  • Easy to Use: using magnetic technology, the probe cover is easy to remove and equip
  • Single-button operation
  • Accurate reading within 1 second
  • You can change the temperature between ℃ and ℉ (black switch under the battery cover)
  • Large backlit LCD screen, allowing measurements in the dark, without disturbing the baby’s sleep
  • Memory recall: press the “M/S” button for 3S to look back the temperature data
  • Mute mode: press the “M/S” button to turn on/off sound
  • Package includes:
    1 x Trustown Forehead and Ear Thermometer
    2 x AAA Batteries
    1 x Portable Pouch
    1 x User Manual

Design & Features

Designed to measure the temperature of both objects and people, Trustown’s infrared thermometer supports both ear and forehead measurements – with the first one being considered by some as slightly more accurate. The overall error margin is 0.2 °C (0.4 °F) – which is more than acceptable.

The ear measurement feature is easy to use too; just remove the cap placed on the sensor, press it slightly and you are done. Note that the display will show a different icon indicating this type of reading. With just a push of a button, you get an accurate reading in one second, in either the Celsius or the Fahrenheit scale. Changing the unit is a bit of a hassle, but nothing too tricky (besides, you are only doing it once): you remove the battery cover, and use the black switch to change it.

The large backlit LCD screen and mute mode setting are very handy (especially for parents), allowing the user to get easy-to-read measurements in the dark without disturbing the baby’s or the toddler’s sleep. The backlight colour screen provides a three colour indication of whether the reading should alarm you or not: green for normal temperatures, orange for slightly beyond normal, and red for temperatures higher than 38 ° C. The thermometer turns off automatically after use but retains previous readings.

Considering its price, this is a great infrared thermometer, but the accompanying instructions are just awful. You’d better figure out by yourselves how the device works and save time and effort.

Pros
  • Cheap
  • Efficient
  • Fast
  • Easy to use
  • Highly portable
  • It measures body and object temperature
  • ℃/ ℉ reading available
  • Memory recall
  • Mute mode
Cons
  • Awful instructions

Our Opinion

Trustown is a good, efficient and fast infrared thermometer, but it comes with truly awfully translated instructions – so, if you go for it, you will need to use your imagination to use it properly.

Design & Features

Ensuring fast and accurate temperature measurements with zero contact, our first pick features a nice ergonomic design, with a new probe structure, a comfortable handle and an overall portable size, which allows you to take it everywhere you might need it.

Easy to use, reliable, hygienic and as accurate as you would expect from a commercial infrared thermometer, it provides precise readings for both objects (rooms, food, water, milk, bath etc.) and human bodies. With a recommended measurement distance of 2 -3.2 Inches (5 – 8cm), it boasts a measurement margin error of just 0.1 ℃.

Its large enough LCD and three-colour backlight colour display allow you to instantly understand whether the measurement should alarm you or not. A green light indicates that the temperature is normal, an orange that it is slightly above normal levels, while the red one indicates a high fever. In that case, it also emits a sound alarm to alert you of the gravity of the situation.

Other handy features include a one-button measurement mode switch (℃/℉), the automatic shut off, and the storage readings.

Any problems with it? Well, for an infrared thermometer of so low a price we have zero complaints, yet we would prefer it if the pair of AAA batteries required would be included in the package.

Pros
  • Fast
  • Accurate
  • Cheap
  • Easy to use
  • Ergonomic grip
  • Three-color backlight display
  • It measures body and object temperature
  • ℃/ ℉ reading available

  • Storage readings
  • Fever alarm
Cons
  • It would be nice if it came with batteries

Our Opinion

Fast, accurate, easy to use, and cheap, our second pick is an ideal choice for parents with small children.

3. Infrared Forehead Thermometer IDOIT

Introduction

Our third pick is also very fast, equally budget-friendly, and allows you to save up to 99 sets of data. Let’s take a closer look.

View on Amazon

At a Glance

  • Suitable for adults, children and babies
  • Equipped with a high-sensitivity infrared sensor microprocessor
  • It reads the temperature value quickly and accurately within 1 second
  • LCD backlight screen, for easy reading even in dark environments
  • Mode/Save button for saving up to 99 sets of data
  • Accuracy range of ±1ºF/0.5ºC
  • Accurate readings from 3 built-in sensors and simple unit switches (Fahrenheit and Celsius)
  • 99 groups of memories, which can be switched between silent and silent modes
  • Multifunctional, suitable for measuring the temperature of both humans and objects, with 2 measurement modes
  • Fever Thermometer System:
    When the measured temperature is below 37.5 ℃, the LCD screen is green and on for 7 seconds
    When the temperature is within 37.5℃-37.9 ℃, the LCD screen turns orange and lights up for 7 seconds
    When the temperature is above 38 ℃), the LCD screen will be red and on for 7 seconds, and 6 alarm beeps will sound
  • Required distance for temperature measurement: 1–2’’ (3-5 cm)
  • Package contains:
    1 x Infrared Thermometer
    1 x packing box
    1 x packing box
    1 x Instruction
    1 x screwdriver
    1 x Velvet Bag
    2 x Screws

Design & Features

Able to take temperature measurements from both bodies and objects, our second pick is suitable for people of all ages, babies, toddlers and grown-ups alike.

Featuring a nice Fever Thermometer System, it indicates the level of temperature and the corresponding health risk with three different colours – green for temperatures below 37.5 ℃, orange for temperatures ranging from 37.5 – 37.9 ℃, and red for any reading above 38 ℃, when also a sound alarms chimes for six times.

The measurement is among the faster in the market, given though a large and easy to read LCD display. On the contrary, it lacks in precision, with an accuracy range of ±1ºF/0.5ºC. It is decent, but if you alarmed by a reading, make sure to verify it with multiple tries. The backlight screen clearly displays the measured value even in dark environments.

On the other hand, for a budget-friendly infrared thermometer like that, it boasts a remarkable data storage capability, being able to record as much as 99 sets of data.

Pros
  • Fast
  • Cheap
  • Easy to use
  • Ergonomic grip
  • Three-color backlight display
  • It measures body and object temperature
  • ℃/ ℉ reading available
  • Automatic shut off
  • Storage up to 99 sets of data
  • Fever alarm
Cons
  • Not very precise

Our Opinion

Fast, cheap, and very easy to use, our third pick allows you to store an amazing number of data sets. Yet, it lacks a bit when it comes to precision.

4. EHH Non-Contact Digital Forehead Infrared Thermometer

Introduction

Another budget-friendly yet efficient option for parents and homeowners, the EHH Infrared Thermometer promises fast and decently accurate readings. Let’s dig deeper.

Design & Features

Easy to use and offering truly rapid measurements (within 1 second), the EHH Infrared Thermometer is designed with a single-push of a button operation. It can measure the temperature of both bodies and objects. Note, though, that its accuracy is far better for the first, with an error margin of no more than ±0.2 °C (±0.4 °F), while that of the object mode rises to ±1.0 °C (1.8°F).

Featuring, as the manufacturer describes it, a “more humanized design”, it is equipped with a Mute function, so it won’t wake up the child or the patient when asleep. Besides, its LED indicator light and aptly sized display, it can be easily used at night or in a pitch black.

Cons
  • Not as precise as pricier models
  • Smaller data storage capacity compared to pricier models

Our Opinion

Fast, cheap, and easy to use, it has all that’s necessary to cater to the needs of a family.

5. Femometer Infrared Thermometer

Introduction

Described as an excellent “choice for families or even hospitals” by the manufacturer, Femometer’s infrared thermometer is affordable, easy to use, and efficient. Let’s check the details.

View on Amazon

At a Glance

  • Brand: Femometer
  • Suitable for both families and medical professionals
  • Equipped with high precision infrared sensor
  • 2 in 1 infrared thermometer, designed for all ages, adults, kids and elders
    Measures temperature of both humans and objects
  • Easy to use button control make – ideal for use with the elderly, adults, children, and babies
  • ℃ and ℉ are easily switchable
  • Instant read – fast measurement with instant reading
  • Clear LCD screen with a fever warning system
    The thermometer for fever indicates temperature status with corresponding emoticons
  • It stores up to 10 sets measurement data to keep track of any variations in the body temperature
    It easily recalls the past 10 sets of data

Design & Features

Neatly designed and equally efficient for people of all ages, with all the necessary features to cater to the needs of a family, the Femometer comes with dual operation mode (forehead and object temperature measurement).

It is a breeze to switch from ℃ to ℉ and vice versa, while the 3-colour backlight screen and the fever sound warning help you understand in a flash the seriousness of the situation. Corresponding emoticons are also used on the display.

Readings are given fast enough (within a second or so). Note that the forehead thermometer does not support continuous measurement to procure more accurate results. Bear in mind that the reading gives a single decimal, which is a bit odd since the Femometer app requests the user to enter temperature results to two decimal places.

Overall, the Femometer is easy to use – provided you figure out first some things by yourself, cause if you don’t know German, you will need some time to do that. Indeed, the included instructions are in German. If you email the manufacturer they will send you a PDF English version, yet it surely should be included in the package. Aside from that, use is a breeze, with its button control and easy settings.

The readings are accurate most of the times (we’ve tested them numerous times with other thermometers), but sometimes may be slightly inconsistent in consecutive measurements.

Another issue is its relatively small storage capacity – just 10 sets of data when other infrared thermometers offer more than 30 or even more. It also lacks a light-up display, which would be useful for taking readings first thing in bed, before getting up. No mute function too, which may bother your partner if he or she is asleep and you want to take several measurements during the night.

It is a good thing, though, that it comes with batteries. Most IR thermometers of this price range don’t.

Pros
  • Affordable
  • Fast
  • Easy to use
  • Three-color backlight display
  • It measures body and object temperature
  • ℃/ ℉ reading available
  • Automatic shut off
  • Data storage
  • It comes with the batteries required
Cons
  • Slightly inconsistent readings
  • Small data storage capacity
  • Included instructions are given in German
  • No mute function

Our Opinion

Another cedent budget-friendly choice for families, the Femometer Infrared Thermometer needs some improvements (and a manual in English) but it will surely do the job.

6. ALERTCARE Forehead Thermometer – Value-for-Money

Introduction

Costing almost twice as much as other efficient infrared thermometers, Alertcare needs to provide sufficient reasons to justify its price. And it certainly does.

View on Amazon

At a Glance

  • Brand: Little Martin’s Drawer
  • Ean: 0619470780055
  • Model: lmdthermo001

    The reading is shown in a large HD display LCD with easy to read numbers
  • Package Contents:
    1 x Infrared Thermometer
    2 x AA Batteries
    1 x User Manual

Design & Features

If you take a gander at Alertcare’s specs, you won’t see anything standing out compared to some of our previous – and much cheaper – picks. So, why does it cost twice as much? The answer is twofold, reliability and consistency.

Indeed, the Alertcare Infrared Thermometer provides much more consistent, thus accurate and reliable readings that its cheaper competitors – and equally fast too, in less than a second. That is why it is suitable both for homeowners and medical professionals.

Aside from that, you get all the bells and whistles we have already seen. It can measure the temperature of both a human body and an object, it easily switches from Celsius to Fahrenheit, it shuts automatically to save energy, it has a fever alert mode (both blinking LCD and sound), and is equipped with a large HD LCD display.

The only con we could find is the relatively small number of data sets stored – namely 32 – but it is more than enough for most cases and the fact that they are so accurate and reliable reduces the number of measurements required for the patient.

Pros
  • Reliable
  • Far more accurate than cheaper models
  • Fast results
  • Easy to use
  • Highly portable
  • It measures body and object temperature
  • ℃/ ℉ reading available
  • Memory recall
  • Mute mode
  • Fever alert
Cons
  • Small number of data sets stored

Our Opinion

Providing consistently accurate and clear readings is Alertcare’s strong point, making it an ideal choice not just for families but also clinics, surgeries and hospitals.

7. Braun BFH-125 Forehead Thermometer -The Best Choice

Infrared Thermometer Buying Guide

We live in times when careful monitoring of our temperature could literally save our lives. For parents, students, professionals, employers and employees – literally everyone – accurate temperature measurements allow them to take action and protect themselves as well as others, especially their loved ones, from infections, viruses and maladies that can pose a serious threat to their health and well-being.

A thermometer also allows you to carefully assess the situation and save yourself precious time and effort, as well as avoid going to the hospital or to a doctor (a place that, especially now, raise the risk of catching a virus) without being absolutely necessary. The last thing you want is to take your kid to the hospital or clinic without actually being necessary.

Mercury thermometers have been for decades the norm, but the danger of swallowing mercury if they broke quickly led to their replacement with the much safer digital thermometers. Still, infrared thermometers take it up a notch. They allow you to measure your temperature or that of another person with minimum or even zero physical contact. This characteristic, along with their accuracy, has made them very popular.

This popularity, on the other hand, has spurred all sorts of manufacturers, of varying reputability and competence, to flood the market with infrared thermometers, making it a bit difficult for someone to pick the right one for his or her needs.

This small article is designed to help you make an intelligent choice. And all intelligent choices hinge on accurate information. Below, you will find several things and factors you need to consider before buying an infrared thermometer.

What is an infrared thermometer?

An infrared thermometer is a thermometer that measures the temperature of a person, animal or object from a portion of the emitted thermal radiation, which is also known as “black-body radiation.” Infrared thermometers are capable of providing accurate results very fast (most of them within 1 or 2 seconds), without any contact with the body or object whose temperature is measured. The amount of infrared energy emitted by a body or object allows thermal radiation technology (which includes, among other devices, infrared thermometers) to infer their temperature within a certain range.

How does an infrared thermometer work?

An infrared thermometer uses infrared rays to measure the amount of heat emitted by a body or an object. It consists of a lens that focuses the infrared thermal radiation on to a detector, which then converts the radiant power to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature.

This process, which takes no more than a second, allows a temperature measurement from a distance without any physical contact whatsoever. Indeed, most infrared thermometers provide an instant reading of the measurement.

Are there other names for infrared thermometers?

Infrared thermometers are also known as “laser thermometers,” because of the laser beam used to target the thermometer. They are also called “non-contact thermometers,” for obvious reasons, as well as “temperature guns” or “thermal guns”, because of their pistol-like shape. Other names are “IR thermometers,” and “pyrometers,” from the Greek word “pyr” that means “fire.”

Are infrared thermometers accurate?

Infrared thermometers provide accurate readings, provided certain conditions are met. For example, in order to operate properly and provide accurate results, the thermometer must be activated within a certain range of distance from a certain body or object. This distance is always specified in the user manual provided by the manufacturer.

In some cases, particularly near ambient temperatures, readings may be subject to error due to the reflection of radiation from a heat source. Depending on the sensitivity of the thermometer, even the person holding it could affect the reading, but this is a very rare incidence, noticed only in poorly constructed IR thermometers.

Are infrared thermometers safe?

Infrared thermometers are safe to use even for infants. In addition to that, their non-contact operation makes it by far the safest choice in cases of infectious diseases, minimising the risk of germ transmission germs from one person to another.

Infrared thermometers are also considered an ideal choice for babies and toddlers, allowing you to measure the temperature of the child even when he or she is sleeping. On top of that, they provide accurate measurements even if the child is a bit restless and has trouble staying still.

How much do infrared thermometers cost?

The price of infrared thermometers ranges from £25 – £30 to more than £100 for more sophisticated models. The price scales up depending on features, measurement accuracy, durability, memory function etc.

How to use an infrared thermometer?

Using an infrared thermometer is very easy. All you have to do is

  • Activate the thermometer.
  • Select the proper mode (object or human body).
  • Pick a temperature measuring unit you prefer (Celsius or Fahrenheit).
  • Point the tip of the thermal gun towards the forehead of the person or the object at the recommended distance.
  • Check the reading and, if possible and desirable, save the measurement for future reference.

What should I consider before buying an infrared thermometer?

There are certain things you need to consider before buying an infrared thermometer. These include the following:

  • Age Group

Some infrared thermometers are designed for specific age groups, for example, children, infants, or adults. Others can accurately take measures from people of any age. Make sure you verify the infrared thermometer’s specs before purchasing it.

  • Accuracy

Accuracy is by far the most important factor to consider in infrared thermometers. Since all brands will claim a flawless accuracy, check the reviews of each one, as well as the reputation of the manufacturer. Reliable brands will provide a margin of error in the specs.

  • Usage

Certain Infrared thermometers can measure the temperature of objects as well as human bodies. If you need such a feature, make sure to check the specs of the infrared thermometer in advance. In most cases, a thermometer with such capabilities will have a different mode for its measurement source, to ensure better accuracy. Be cautious with infrared thermometers that claim both functions but do not have a different mode for each one.

  • Design/ Ease of Use

Ease of use is of the essence, especially for people without medical experience. Features that are considered essential for convenient use include:

  • One-touch measurements and setting adjustments,
  • an ergonomic grip that allows the user to hold the thermometer steady during operation and take accurate measurements,
  • a clear, easy to read display,
  • sound and colour alarms for non-normal measurements, allowing the user to understand the reading and act accordingly,
  • lighting, that allows use in dark environments,
  • the option of deactivating the sound alert, to enable use for children or patients while they are asleep and without disturbing them.
  • Unit of measurement

Most infrared thermometers provide readings in both Celsius and Fahrenheit, but you need to verify that in the specs and make sure that you check the measuring unit and pick the one that you are convenient with. In thermometers that have both options, the user is able to pick the one he or she prefers.

  • Time of response
