How to Choose the Right Infrared Thermometer:

What is the temperature range of the target?
ProSource offers a variety of temperature ranges. Choose the temperature range to meet your application requirements.

How large is the target? How close can you get?
The field of view of an infrared thermometer is similar to that of a flashlight, the further the object is away fro the flashlight, then the bigger the diameter of the beam. The further you are from your target, the larger the area the infrared thermometer is measuring. Optical resolution is defined by the ratio between the distance from the object being measured to the size of the object being measured (D:S). The greater the D:S ratio, the higher the optical resolution. A thermometer with a higher resolution allows you to measure smaller objects from greater distances. Choose the ratio that best meets your application requirements.

What material will you be measuring?
Infrared thermometers work by measuring emitted infrared (IR) energy from a target object and translating the value into temperature. Emissivity is the ability of the material surface to emit IR energy. Some of our thermometers have adjustable emissivity to ensure accuracy when measuring other materials such as metals, glass, and thin film plastics. Most organic, painted or oxidized surfaces have emissivity values close to 0.95. A fixed emissivity of 0.95 cover 90% of all surface applications. Choose preset or adjustable emissivity.
