How do you determine the temperature measurement range of an infrared thermometer?
Determine the temperature measurement range: The temperature measurement range is the most important performance indicator of the thermometer. Some thermometer products can reach a range of -50 ℃ -+3000 ℃, but this cannot be achieved by one model of infrared thermometer. Each model of thermometer has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurate and comprehensive, neither too narrow nor too wide. According to the blackbody radiation law, the change in radiation energy caused by temperature in the short wavelength of the spectrum will exceed the change in radiation energy caused by emissivity error. Therefore, when measuring temperature, it is advisable to choose short waves as much as possible. Generally speaking, the narrower the temperature measurement range, the higher the resolution of the output signal for monitoring temperature, and the easier it is to solve the accuracy and reliability. If the temperature measurement range is too wide, it will reduce the temperature measurement accuracy. For example, if the target temperature being measured is 1000 ℃, 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, and 3i1M. If measurement accuracy is the main factor, it is best to choose 2M or 1M models, because if 3iLR models are used, their temperature measurement range is very wide, and their high temperature measurement performance will be worse; If the user needs to take into account the low-temperature target in addition to measuring 1000 ℃, then they have to choose 3iLR3.
