One purpose of this procedure is to use it for Intermediate Check activity, part of quality control procedure to ensure accuracy and proper functioning of your instrument. If you are going to calibrate infrared thermometers, make sure that the calibrator you use is calibrated on the same wavelength that you are measuring. Dotake the measurements as quickly as possible, to prevent the surface temperature from changing. Fill a glass halfway with ice cubes and half-way with cold water. Black bodies approximate zero reflected ambient radiation and therefore the unimpeded emission of infrared energy for a given emissivity value (typically 0.95). Steam and the evaporative cooling and condensation that accompany it make it very difficult to get an accurate infrared measurement of a boiling liquid. Step: 4 Make a well of exposed water where no ice is floating or press the ice below, so there is a level of exposed water at the glasss peak. Measuring with an IR thermometer is an optical measurement, so just like binoculars and telescopes there is a field of view. I appreciate it. Some of the advantages of infrared thermometers are stated below. The measurement time should be ten times longer that the infrared thermometer's response time, typically five seconds for Fluke infrared thermometers. The alarm temperature can be set to 38C (100.4F). The measurement should be initiated. Figure 8. They also should be able to switch between adjusted mode and unadjusted mode, or measurement mode. Uncertainty analysis is necessary for any calibration. Set the 4180 to 37 C (98.6 F) and set the 4180 apparent emissivity setting to 0.98, the emissivity of skin, which also should be the emissivity of the DUT (device under test) thermometer. If you need more accuracy at a higher range, it is advisable to send your IR thermometer to a qualified calibration lab.
