Are You Sure You Need an Infrared Thermometer?

An infrared thermometer has a long list of benefits. It is non-contact and does not have a mechanical effect on the measuring surface. It is also inexpensive and easy to use, but you should be careful when targeting it. It can give you an accurate reading as long as the measurement surface and device are in the line of sight (LOS). Finally, the battery life of an infrared thermometer is a crucial feature.

It means that they can be used on most foods and materials. Other adjustable-emissivity models can be calibrated to match the type of surface to be measured. In addition, they are generally accurate to within a few degrees. However, if you are measuring a non-organic surface, you will need to adjust the emissivity setting accordingly.

An IR thermometer is an excellent tool on hand, especially when working in a contaminated area. This device can measure the temperature of a metal surface without contaminating it, which is ideal for a physician’s office. It is also a valuable tool for checking the temperature of medicines, medical devices, and food. Furthermore, IR thermometers store real-time readings and can be erased when you need to do so.

You’ve probably heard of an infrared thermometer, but are you sure you need one? This article will discuss what an IR thermometer is and its main features. You’ll learn how these instruments work, their temperature range, and what applications they can serve. This article will also discuss the advantages of an IR thermometer, including its Field of View, Accuracy, and Applications. Learn more about instrumentchoice.com.au infrared thermometer.

Field of view of an infrared thermometer

The field of view of an infrared thermometer is a critical component of the accuracy of its readings. A standard method for determining the size of a lot of thought is the distance to the spot or the D:S ratio. This value is directly proportional to the sophistication of the optical system. Unfortunately, there is no industry standard for D:S ratios and field of view diagrams, so manufacturers use various methods.

Temperature range of an infrared thermometer

The distance to the object that the infrared thermometer can measure is one of the most critical characteristics of determining the measurement’s accuracy. This factor will vary depending on the model. A general rule of thumb is that if the distance to the object exceeds three meters, the thermometer is not accurate. However, if you must measure a very far thing, you should look for a model with a more extended range.

Another critical feature to consider is the distance to the target. An infrared thermometer that measures a large area close to the range will give you a more accurate reading. The D:S ratio refers to the distance from the target to the spot on the infrared thermometer. This ratio can range from 1:1 on inexpensive models to 60:1 on high-end ones. The chart below shows examples of field-of-view diameter for different D:S ratios.

Accuracy of infrared thermometer readings

To maximise the accuracy of infrared thermometer readings, calibrate the device with a Fluke IR calibrator. It is essential if you frequently use your thermometer for temperature measurements. To ensure accuracy, make sure that the lens is scratch-free, and calibrate the device to the ambient temperature of the calibration area. You can also learn more about infrared thermometer calibration by reading Fluke’s technical papers.

Infrared thermometers are relatively accurate for most objects. However, reflective surfaces, such as glossy paint, can pose a challenge. Try using non-reflective tape to protect shiny objects or a flat paint surface to prevent glare from affecting the thermometer’s readings. A non-reflective tape or paint can help improve the accuracy of infrared thermometer readings.


Infrared thermometers can be used in many different applications. For example, they can be life-savers when a person is undergoing a coronavirus infection. They can also help the medical community determine the temperature of heated liquids and solids at room temperature. These thermometers can detect temperatures of up to 110 degrees Celsius. Some types are even used for determining body temperature in colder climates. Learn more about instrumentchoice.com.au infrared thermometer.
