How to Select Infrared Thermometer Model

The selection of Infrared Thermometer can be divided into three aspects:

(3) Other options, such as ease of use, maintenance and calibration performance, and price, also have a certain impact on the choice of thermometer.

With the continuous development of technology, the best design and new progress of infrared thermometers provide users with various functions and multi-purpose instruments, which expands the choice. Other options, such as ease of use, maintenance and calibration performance, and price. When selecting the thermometer model, first determine the measurement requirements, such as the target temperature to be measured, the size of the target to be measured, the measurement distance, the target material to be measured, the environment of the target, the response speed, the measurement accuracy, whether it is portable or online, etc. ; In the comparison of existing various types of thermometers, select the instrument model that can meet the above requirements; choose the best match in performance, function and price among many models that can meet the above requirements.

Selection of infrared thermometer to determine the temperature measurement range

Determine the temperature measurement range: The temperature measurement range is the most important performance index of the thermometer. For example, the coverage of Raytek products is -50 ℃-+ 3000 ℃, but this cannot be done by one type of infrared thermometer. Each type 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 law of blackbody radiation, in the short-wavelength range of the spectrum, the change in radiant energy caused by temperature will exceed the change in radiant energy caused by the emissivity error. Therefore, it is better to use short-wave as much as possible when measuring temperature. In general, the narrower the temperature measurement range, the higher the resolution of the output signal for monitoring temperature, and the accuracy and reliability are easy to solve. If the temperature measurement range is too wide, it will reduce the temperature measurement accuracy. For example, if the measured target temperature is 1000 degrees Celsius, first determine whether it is online or portable, if it is portable. There are many models that meet this temperature, such as 3iLR3, 3i2M, 3i1M. If the measurement accuracy is the main, it is better to choose the 2M or 1M model, because if the 3iLR type is used, the temperature measurement range is very wide, the high temperature measurement performance will be worse; if the user has to take care of the goal of measuring 1000 degrees Celsius For low temperature targets, you have to choose 3iLR3.
