Difference between human thermometer and industrial thermometer
Human infrared thermometers are mainly used to measure the temperature of the human body, while industrial infrared thermometers, as the name suggests, are mainly used in the industrial sector. However, it must be clarified that there is no specialized medical or industrial infrared thermometer, because the manufacturing principle of infrared thermometer are the same. There are only high-precision, high-distance coefficient ratio, high-performance infrared thermometer and low-precision, low distance coefficient ratio and low performance of the infrared thermometer. As long as the emissivity of the infrared thermometer is set at 0.95 (human skin emissivity is generally this value, even if there is a difference, the impact is only within 0.2 degrees), is in line with the requirements of human body temperature measurement.
First, the human body infrared thermometer temperature measurement interval is small, 30 - 42.5 degrees, but the display is highly accurate. Industrial infrared thermometer range, such as measuring -50 - 2200 degrees.
Second, the human infrared thermometer needs to be close to the human body, 1-15cm or less, industrial infrared thermometer to be greater than 1M, such as measuring the temperature of steel, people can not be too close, some need to be about 10M. Measurement of near and far, mainly thermometer issued by the infrared wave strength. Human infrared thermometer infrared wave is too strong will be harmful to the human body, but also do not need.
Therefore, we can choose the right thermometer according to the need can be divided into three aspects: performance indicators, such as temperature range, spot size, operating wavelength, measurement accuracy, response time, etc.; environmental and operating conditions, such as ambient temperature, window, display and output, protection accessories, etc.; other choices, such as ease of use, maintenance and calibration performance, as well as price, etc., but also on the selection of infrared pyrometers Have a certain impact.
