Industrial IR thermometrs are NOT designed for measuring human body temperature and should not be used, but IR thermometers designed for use on humans may be used. You need mandatory and non-mandatory calibration equipment to make the calibration process accurate and reliable. Record the temperature. The concave portion at the top of the display panel is within 1 mm of the calibrator surface. Centering the infrared thermometer on the calibrator surface At this point, a measurement is ready to be made. Welcome to the field of Metrology. Using an IR thermometer at hot or cold temperatures will increase the possibility of thermal instability. Dontchange the temperature surrounding the comparator before validation or the surface temperature may differ from the internal temperature. A thermal imager is an infrared thermometer that takes a thermal image of a body rather than measuring just on a spot like a regular IR thermometer does. For example, you can test it at 41F [5C] and 140F [60C]. Third, the position of the technician performing the calibration should be considered, since he/she influences the reflected temperature. Dontforget that the thermometers require time to acclimatise to a different environment. Figure 2. If you perform the test correctly, and your infrared thermometer is properly calibrated, it should read within your unit's stated accuracy specification of 32.0F (0.0C). Centering the infrared thermometer on the calibrator surface. The radiation source should be set to the desired calibration temperature and should be allowed to stabilize. 6. For calibrations at temperature below 50 C, a divider may need to be emplaced between the technician and the radiation source (see Figure 7). Stir one more, then put your thermometer into the glass without touching the edges. His career with Fluke and the former Hart Scientific spans 18 years and includes work in the Temperature Calibration Service Department and the Primary Temperature Calibration Laboratory, both in American Fork, Utah. Hi Sir Eric,Very True. If your thermometer has a laser pointer built into it, you should turn it off because you dont want to shine it in someones eyes.

Calibrating emissivity to the right value for the type of surface whose temperature you are measuring improves accuracy. As seen inthis blog poston the accuracies and limitations of infrared, emissivity plays a huge role when calibrating IR thermometers. Scheme I (Contact) and Scheme II (Radiometric) Traceability. This is an especially important consideration when bringing a thermometer in from the outside. The thermometer comparator consists of an aluminium cup with a solid matte black base. IR thermometer for medical or for human use has higher accuracy compared to industrial IR thermometers. The result should be equal or close to 32.0F (0.0C) since it is ideal. Wait for ten minutes. It may be a good idea to move the IR thermometer closer and further from the target by a few cm to verify readings do not change due to a change in distance. It has tolerances that are far more strict than that of industrial use. If you are using your IR thermometer for higher ranges (above 100 deg C) with strict tolerance, you need to send it to a qualified calibration lab. When I refer to a scanning system, I mean a system that uses a thermal imager, perhaps something in the entry of an office building, that takes a thermal image of people as they walk into the building. Wait for the water to come to a continuous rolling boil. In most infrared thermometers, you hold a button for a couple of seconds to access the calibration settings. If your infrared thermometer has a bigger deviation from this range, itll require calibration. Calculate DUT error by subtracting DUT average from the 4180 average. We have heard from many Fluke customers who ask about how to calibrate and verify IR forehead thermometers. We want to help you with the simpler calibration method, which is to use a Fluke 4180 Precision Infrared Calibrator in its standard configuration.

The positioning of equipment within the laboratory is critical. For one measurement, it should take the calibration technician no longer than 15 seconds. An infrared thermometer is a non-contact thermometer since it doesn't touch the surface being measured. After washing, drain the water in the ice properly. Low cost forehead thermometers may have such poor optics the thermometer may have to be almost touching the forehead to get reliable readings. Different surfaces have varying emissivity values between one and zero. If the infrared thermometer has a reflected temperature setting, it should be set to the radiation sources reflected temperature. Controlling Reflected Temperatures for Lower Temperature Calibrations. Your reading should stay within these limits in order to be acceptable. The transfer standard is used to calibrate the thermal radiation source. The goal is to create an ice bath with uniform temperature. And you can use a comparator to verify your result. For other manufacturers models, this information should come from the infrared thermometer manufacturer or be determined by experimentation. Determine if conditions are optimal for use. The default emissivity settings of most IR thermometer is 0.95. Some models include plug in thermometers which you can use to test ice, boiling water (along with an altitude adjustment table), and calibrate against them. The measurement time should be ten times longer that the infrared thermometers response time, typically five seconds for Fluke infrared thermometers. Mike Coleman is Director of Temperature Metrology for Fluke Calibration. For example, Frank Liebmann is a recognized expert in the field, and he has contributed many technical articles and scientific papers on this subject. Fill a glass or deep container that is large enough to accommodate the thermometer probe with crushed ice. This is where the importance of IR thermometer calibration comes in. For those who do not know the conversion here is a simple formula for this purpose: (T (C) = (T (F) - 32) 5/9). Many IR thermometers designed for human fever scanning have entered the market to address the COVID-19 need but sadly, some of the basic information that you need in order to choose a thermometer or assess its reliability is not easily available. Well, you can do it by following some rules and steps. Hi Valmik,you are welcome. Fill a glass with crushed ice.
