How Do Infrared Thermometers Work?

An IR thermometer is great for measuring temperatures on the object and surfaces without contacting it. Each of the objects around us radiates some thermal energy. The hotter something is, the higher the thermal energy it will possess.  IR thermometers have been equipped with detectors that can transform the thermal energies into an electronic signal that can be seen on a screen in a few seconds. The best thermometer also has a laser pointer for measuring the accurate temperature of the object in the target.  Its high speed and versatility make Infrared thermometers one of the essential tools for several homes, commercial and industrial applications.

Infrared Thermometers Buying Guide: Factors you should consider before purchasing Infrared Thermometers:

·       Overall Features:

There are varied types of IR thermometer catering to different requirements of the customers. But some of the features can be seen to be common in them. One of the important features remains the LCD screen display as the readings being shown should be clear. Additionally, some of the features also include data log capabilities so that proper records can be maintained. Other features that you might want to look into can be laser sighting and emissivity.

·       Purpose of Use:

Each of the IR thermometers gets designed for serving a specific purpose. Some of them are used for medical uses while others for industrial. Then some thermometers are used for determining temperature objects situated at a distance. Therefore you must choose a thermometer based upon the purpose.

·       Temperature Range:

Depending on the task, the temperatures of a thermometer vary on the temperature range it has. For example, most of the general models can measure temperatures from -50 to about 400 degrees Celsius. While the professional ones can measure even much higher temperatures up to 750 degrees.

·       Speed and Accuracy:

All of the thermometers that we mention on the list offer you quick and accurate results. The advanced technology makes them perfect or professional usage, and the accurate results are given because of the adjustable emissivity and good IR sensors. Choose the tool that is according to your precision requirements.

·       Cost:

This is one of the essential factors that one should observe before making a purchase. Even if you have a low budget, go for good accuracy, and provide basic features. This will make sure that purpose is served as per your needs.

·       Memory Functions:

All of the latest models to come with memory functions. The feature allows you to see the last reading for reference. This will be a good feature to have in case the body temperature is constantly varying. Some of the latest ones even can store around 20 readings at one time.

·       Backlit LCD Display:

Or reading the temperature clearly, it is good to go for a forehead IR thermometer that comes with a big LCD so that it’s easy for you to read the numbers. When the display has a backlit feature, it ensures proper illumination, and you can understand the readings correctly in dark conditions.

·       Sound:

Most of the thermometers that we mentioned on the list do make a sound. This indicates the time when it’s ready to show temperature. The sound offers convenience for the most part but can be an issue if the child is sleeping. Go for the one that has modes of silence or mute as well.

·       Indication for Fever Alert:

For making your work easier, some of the thermometers also come with a fever alert feature. This allows the user to understand when the body temperature is above the normal range.

·       Auto Shut-off and Battery Life:

There is a need for auto-shutoff as these thermometers depend on batteries. If you forget to switch it off, the battery tends to get wasted with time. Therefore there are models available that have this feature that makes sure there is prolonged battery life when the device isn’t touched for 30 seconds.

Some of the IR thermometers depend on cell battery while others might use AAA or AA batteries. Regardless of the source, battery life is another important aspect that you should be taking a look at. Some of them are going to last longer than others. We recommend that you always keep a pair of extra batteries in case of emergencies. It is always a good idea to be prepared beforehand when it comes to health.

Are Infrared Thermometers Accurate?

One of the most important factors while you consider purchasing Infrared thermometers, is the accuracy. This is because wrong reading might lead to a false diagnosis and can further complicate the health issue. Most of the thermometers do use infrared technology that gives you accurate readings. However, in case you are confused, try taking readings at least thrice at the same time. Then a comparison can be made as per the recordings.

Some of the thermometers promise of offering accurate reading, but small deflection can still be seen. Most of the companies do provide this information on the product itself and are honest. This makes calibration or accurate calculations easier. So you must check for such details for sure.

Surfaces you’re Measuring (Emissivity)

Infrared thermometers can measure external temperature. Emissivity has been related to reflectivity of the object surface that’s being scanned. These thermometers can feature fixed emissivity of about 0.95 that’s perfect for solid surfaces like metal, walls, pipes, and more.

Fixed emissivity might result in issues that can occur with a reflective object like glass, oil, or liquid. Hence, it will be the best choice to go for professional models that provide variable emissivity. This will allow you calibration for each of the surfaces for precise readouts.

Ease of Use and Reliability

The basic need or an IR thermometer is ease of use. Even when you have to use several times, the accuracy in reading shouldn’t change. There should be features of saving the previous readings so that one can make a comparison if needed. The switch-on option must be easy, and the readings need to be recorded in a few seconds. The tool should also be easy to carry while you are on the go.

FAQ on Infrared (IR) Thermometers

Are IR thermometers safe?

The clinical thermometers are completely safe to be used for anyone. This includes adults, children, and babies as long as one doesn’t point the laser towards the eyes. These are non-contact devices that help you to measure the temperature from a safer distance.

What are the temperatures that IR thermometers measure?

Depending on the type of model that you have got, the range of temperature measurement varies. The clinical IR thermometers made for measuring body temperatures have better accuracy and can measure between the range of 32 to 42 degrees Celsius. Industrial thermometers have higher and extensive temperature ranges and can lie between -50 to 1000 degrees Celsius.

What is the response time that one should expect?

Most of the IR thermometers are fast. Some of them can provide a reading within one second.

What is the greatest distance that one can remain from the target for an accurate result?

This is one function that depends on the thermometer optics of the one that you purchased. Make use of the distance and size ratio to find the maximum distance that you can be around from your target. Typically the maximum distance that one of these thermometers allows is about 30 meters, which also depends on the atmospheric conditions.

How to clean an Infrared Thermometer?

For providing accurate readings, IR thermometers need to be cleaned. You can make use of clean cloth, or a cotton swab dipped in water or rubbing alcohol. First, carefully wipe the lens and then the thermometer body. Make sure that before using it again, it’s completely dried. Never use chemicals, or sop or submerge the thermometer into the water.
