Infrared thermometers can be purchased from three sources
When choosing an infrared thermometer, it is generally necessary to focus on the following three aspects for inspection:
a. In terms of performance indicators, such as temperature range, spot size, working wavelength, measurement accuracy, window, display and output, response time, protective accessories, etc;
b. In terms of environment and working conditions, such as environmental temperature, windows, display and output, and protective accessories;
c. Other options, such as ease of use, maintenance and calibration performance, and price, also have a certain impact on the selection of thermometers.
With the continuous development of technology, the optimal design and new advancements of infrared thermometers provide users with a variety of functional and versatile instruments, expanding their choices. Other options include ease of use, maintenance and calibration performance, and price. When selecting a thermometer model, the measurement requirements should be determined first, such as the temperature of the target being measured, the size of the target being measured, the measurement distance, the material of the target being measured, the environment in which the target is located, response speed, measurement accuracy, whether to use portable or online, etc; Select the instrument model that can meet the above requirements from the comparison of various existing models of thermometers; Choose the best combination in terms of performance, functionality, and price among many models that can meet the above requirements.
How to use an infrared thermometer for temperature measurement
1. Only measuring surface temperature, infrared thermometer cannot measure internal temperature.
2. Temperature measurement cannot be carried out through glass as it has special reflection and transmission characteristics, and infrared temperature readings are not allowed. But temperature can be measured through an infrared window. Infrared thermometers are not suitable for measuring temperature on bright or polished metal surfaces (such as stainless steel, aluminum, etc.).
3. To locate a hotspot, aim the instrument at the target and then scan up and down on the target until the hotspot is identified.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It obstructs the optical system of the instrument and affects temperature measurement.
5. The ambient temperature, if the thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allows the instrument to adjust to the new ambient temperature within 20 minutes.
