Talking about the performance of infrared thermometer with electric heating tube
Infrared thermometers measure the surface temperature of a target object by receiving energy emitted, reflected, and transmitted. The detection element in the thermometer transmits the collected energy information to the microprocessor for processing, and then converts it into a temperature reading for display. In models with a laser sight, the laser sight is used for aiming only. Its performance description is shown in Table 1. PT, TI series portable thermometers developed by Beijing Infrared Times.

Infrared Thermometer Performance In order to obtain accurate temperature readings, the distance between the thermometer and the test target must be within a suitable range. The so-called "spot size" is the area of the measurement point of the thermometer. The farther you are from the target, the larger the spot size. The ratio of distance to spot size, or D:S.
Measuring distance and spot size
When determining the measurement distance, ensure that the target diameter is equal to or greater than the measured spot size. 4. Correct selection of infrared thermometer
The selection of infrared thermometers can be divided into three aspects: the performance of infrared thermometers for electric heating tubes
(1) Performance indicators, such as temperature range, spot size, working wavelength, measurement accuracy, window, display and output, response time, protection accessories, etc.;
(2) Environmental and working conditions, such as ambient temperature, windows, display and output, protective accessories, etc.;
(3) Other options, such as ease of use, maintenance and calibration performance, and price, also have a certain impact on the choice of thermometers.
With the continuous development of technology and technology, the best design and new progress of infrared thermometers provide users with various functional and multi-purpose instruments, expanding the choice. Other selection aspects such as ease of use, repair and calibration capabilities, and price. When choosing a thermometer model, you should first determine the measurement requirements, such as the temperature of the target to be measured, the size of the target to be measured, the measurement distance, the material of the target to be measured, the environment of the target, response speed, measurement accuracy, portable or online, etc. ;In the comparison of various existing models of thermometers, select the instrument model that can meet the above requirements; choose the best match in terms of performance, function and price among many models that can meet the above requirements.
