How to determine the temperature range of the infrared thermometer?
Determine the temperature measurement range: The temperature measurement range is the most important performance index of the thermometer. Some thermometer products have a range of -50°C -+3000°C, but this cannot be done by one type of infrared thermometer. Each type of thermometer has its own specific temperature range. Therefore, the user's measured temperature range must be considered accurately and comprehensively, neither too narrow nor too wide. According to the law of blackbody radiation, the change of radiation energy caused by temperature in the short-wave band of the spectrum will exceed the change of radiation energy caused by emissivity error. Therefore, it is better to use short-wave as much as possible when measuring temperature. Generally speaking, the narrower the temperature measurement range is, the higher the resolution of the output signal of the temperature monitoring is, and the accuracy and reliability are easy to solve. If the temperature measurement range is too wide, the temperature measurement accuracy will be reduced. For example, if the measured target temperature is 1000°C, first determine whether it is online or portable, and if it is portable. There are many models that meet this temperature, such as 3iLR3, 3i2M, 3i1M. If the measurement accuracy is the main thing, it is better to choose the 2M or 1M type, because if the 3iLR type is used, the temperature measurement range is very wide, and the high temperature measurement performance will be poor; For low temperature targets, we have to choose 3iLR3.
