Correct calibration method and process for UV aging Test Chamber

The UV aging Test Chamber is a device used to simulate the sunlight ultraviolet radiation environment and conduct accelerated aging tests on materials. In order to ensure the accuracy of the test results, it is necessary to calibrate the UV aging Test Chamber.

Here are some common calibration steps:

1. Calibration of UV radiation intensity

The ultraviolet radiation intensity refers to the radiation intensity produced by the ultraviolet lamp. Typically measured with a calibrated radiometer to ensure compliance with specified standards. When calibrating, it is necessary to place the radiometer in the irradiation area of the UV lamp and record the measurement results. Then, adjust the distance of the ultraviolet lamp tube or replace the lamp tube according to the measurement results, so that the ultraviolet radiation intensity meets the standard requirements.

2. Temperature control calibration

Temperature control refers to controlling the temperature in the Test Chamber within the specified range. In order to ensure the accuracy of the temperature, it is necessary to use a calibrated thermometer or temperature sensor to measure the temperature in the Test Chamber at different positions, and record the measurement results. Then, adjust the temperature controller in the box according to the measurement results so that it can accurately control the temperature.

3. Humidity control calibration

Humidity control refers to controlling the humidity in the Test Chamber within the specified range. In order to ensure the accuracy of the humidity, it is necessary to use a calibrated hygrometer or humidity sensor to measure the humidity in the Test Chamber at different locations and record the measurement results. Then, adjust the humidity controller in the box according to the measurement results so that it can accurately control the humidity.

Calibration needs to follow standard operating procedures and operate according to the instrument's instruction manual. Calibration equipment such as radiometers, thermometers, and hygrometers should be inspected and calibrated regularly to ensure their accuracy and reliability. It is recommended to calibrate the UV aging Test Chamber regularly to ensure the accuracy and reliability of the instrument.
