红外测温仪的测温是以普朗克辐射定律为理论根据,通过对被测目标红外辐射能量进行测量,经黑体标定,从而确定被测目标温度的。红外测温仪具有非接触式测量、响应速度快、不扰动被测目标温度分布场的特点。对于一些不能用接触方式测量的目标、活动目标,以及温度变化迅速的目标的温度测量,红外测温仪有其独特的效果。它为现代测温技术的发展提供了一种新的测量手段。 Infrared thermometer temperature measurement is based on Planck’s radiation law as the theoretical basis, by measuring the target infrared radiation energy measurement, calibration by the black body, so as to determine the measured target temperature. Infrared thermometer with non-contact measurement, fast response, does not perturb the measured temperature distribution of the target field characteristics. Infrared thermometers have their unique effect on temperature measurements of targets that can not be measured by touch, activity targets, and temperature targets. It provides a new measure for the development of modern temperature measurement technology.
