The control system of the ozone aging test chamber is an important part of ensuring the accuracy of the test results and requires regular calibration. The following are some common methods for calibrating the control system of the ozone aging test chamber:
1. Temperature calibration: First, place the temperature probe inside the device, set the temperature of the test chamber to the standard temperature (such as 25°C), and read the actual temperature value after the device is stable. Compare the actual temperature value with the standard temperature value, if there is a deviation, adjust the temperature by adjusting the control parameters of the thermostat.
2. Humidity calibration: place the humidity probe inside the device, set the humidity of the test chamber to the standard humidity (such as 50%), and read the actual humidity value after the device is stable. Compare the actual humidity value with the standard humidity value, if there is any deviation, adjust the humidity by adjusting the control parameters of the humidity controller.
3. Ozone calibration: Use standard ozone concentration gas or a standard ozone generator to set the ozone concentration to a standard value (such as 50ppm), and read the actual ozone concentration value after the device is stable. Compare the actual ozone concentration value with the standard ozone concentration value, if there is a deviation, adjust the ozone concentration by adjusting the output of the ozone generator or the air flow.
It should be noted that when calibrating the control system, it should be operated according to the requirements of the equipment manual, and standard calibration equipment and standard gases should be used to ensure the accuracy and reliability of the test results. At the same time, the equipment should be maintained and maintained regularly to ensure the normal operation of the equipment and the accuracy of the test results.
