Centering the infrared thermometer on the calibrator surface At this point, a measurement is ready to be made. A perfect blackbody has an emissivity of 1. It is best to calibrate your infrared thermometer at more than one temperature (at 41F [5C] and 140F [60C] for example) and the Infrared Comparator Cup makes it easy. If the calibration is to be done with a dry gas purge, the purge shall be set up before the radiation source stabilizes. The further away you are from something, the larger the field of view, and eventually you start getting temperatures from surroundings around the object that youre measuring. If the thermometer is a dial thermometer, allow 1-2 minutes for temperature calibration. Add ice-cold water and stir to mix it well with the ice. Some companies are screening people coming through the front door with a process that includes a contact thermometer; that is, if they see an anomaly on a persons temperature when taken with a non-contact infrared thermometer, they take that person to another area where they use a contact thermometer to make a better measurement. I dont know how much the difference is but the user must take that into account. Once the distance is set, the infrared thermometer should be centered on the calibrator surface. A more complicated low-uncertainty method using a reference thermometer will be described in detail in future articles and application notes along with advice for calculating measurement uncertainty. It should be noted that Fluke infrared thermometers do not have a reflected temperature setting. The best standard for choosing an IR thermometer that I have seen is ASTM E 1965-98. But the user will get an second measurement (calibration) point.But: we speake about a tolerance of +/- 2K or 2% of reading what ever is greater for an industrial measurement device. Nice! The next step is to align the infrared thermometer. ThermoWorks 2023. An object's emissivity refers to the way it gives off thermal radiation. ASTM requires that if you are going to use an IR thermometer for measuring skin temperature, it must be accurate to within 0.3 C (0.54 F). Check if the temperature reading on the infrared thermometer matches that of the conventional thermometer. This could take any amount of time, depending on the response time of the inserted probe. If a Fluke 4180 or 4181 is being used, this correction can be made automatically by the instrument. Figure 1. Fill a glass halfway with ice cubes and half-way with cold water. Measurements should be taken from this point as shown in Figure 8. When cleaning, just meticulously wipe the lens first and then the main body of the thermometer. In most infrared thermometers, you hold a button for a couple of seconds to access the calibration settings. If you are interested in being informed about that, pleasesign up for our email list.
