Precautions For Using Infrared Thermometer
Leave a message
1. Avoid environmental interference
The measurement results of infrared thermometers may be affected by environmental factors, such as strong electromagnetic fields, radiation from high-temperature objects, smoke, dust, etc. These interference factors should be avoided as much as possible during measurement.
If there are other high-temperature objects in the measurement environment, ensure that the thermometer is not affected by their radiation.
2. Correctly select the measurement point
For objects of different shapes and materials, appropriate measurement points should be selected. For example, for objects with smooth surfaces, you can choose to measure at their center; for objects with rough surfaces, you can choose to measure at multiple points and take the average.
Avoid measuring the edges, corners, or parts of objects with obvious differences in heat conduction, as the temperature of these parts may be inconsistent with the overall temperature of the object.
3. Pay attention to the characteristics of the object being measured
Objects of different materials have different reflection and absorption characteristics for infrared rays, which may affect the measurement results of the thermometer. For example, metal surfaces have strong reflection of infrared rays, while non-metallic surfaces such as plastics and wood have strong absorption of infrared rays.
When measuring objects of different materials, you can refer to the manual of the thermometer to understand its measurement accuracy and scope of application for different materials.
4. Calibrate the thermometer regularly
In order to ensure the measurement accuracy of the thermometer, it should be calibrated regularly. The thermometer can be calibrated using a standard temperature source (such as a constant temperature water bath, a black body furnace, etc.).
The frequency of calibration depends on the frequency of use and accuracy requirements of the thermometer. Generally speaking, it is recommended to calibrate at least once a year.
