Infrared thermometer correct choice
Selection of infrared thermometer can be divided into 3 aspects:
(1) Performance indicators, such as temperature range, spot size, operating wavelength, measurement accuracy, window, display and output, response time, protection accessories, etc.;
(2) Environmental and working conditions, such as ambient temperature, window, display and output, protection accessories;
(3) other selection aspects, such as ease of use, maintenance and calibration performance and price, also have a certain impact on the choice of pyrometer.
With the technology and continuous development, infrared thermometer best design and new advances provide users with a variety of functions and multi-purpose instruments, expanding the choice. Other aspects of choice, such as ease of use, maintenance and calibration performance and price. In the selection of pyrometer models should first determine the measurement requirements, such as the measured target temperature, the measured target size, measurement distance, the measured target material, the target environment, response speed, measurement accuracy, with portable or online and so on; in the existing various models of pyrometer comparison, selected to meet the above requirements of the instrument model; in the many models that can meet the above requirements to select the model in terms of performance, functionality In the many models that can meet the above requirements to choose the best performance, functionality and price of the match.
Determine the temperature range
Determine the temperature range: the temperature range is one of the most important performance indicators of the pyrometer. Products cover the range of -50 ℃ - +3000 ℃, but this can not be a model of infrared thermometer to complete. Each model of pyrometer has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurately and thoroughly, neither too narrow nor too wide. According to the law of blackbody radiation, in the short wavelengths of the spectrum by the temperature caused by the change in radiant energy will exceed the emissivity error caused by the change in radiant energy, therefore, temperature measurement should try to choose the better short-wave. Generally speaking, the narrower the temperature measurement range, the higher the resolution of the output signal to monitor the temperature, and the accuracy and reliability are easy to solve. Temperature measurement range is too wide, it will reduce the accuracy of temperature measurement. For example, if the measured target temperature is 1000 degrees Celsius, first determine whether the online or portable, if portable. To meet this temperature of many models, such as 3iLR3, 3i2M, 3i1M. If the measurement accuracy is the main, it is best to choose 2M or 1M models, because if you choose the 3iLR type, the temperature measurement range is very wide, then the performance of high-temperature measurements will be poorer; if the user in addition to measuring the target of 1,000 degrees Celsius, but also to take care of the target of the low-temperature, then you have to choose the 3iLR3.
