How to calibrate the irradiance of air-cooled and water-cooled xenon lamp aging test chambers? Dongguan Ai Sihao Testing Instrument Co., Ltd. will provide a detailed explanation of the calibration principles and procedures for these two types of equipment.

For air-cooled xenon lamp aging test chambers (flat type), the irradiance calibration system uses a separate radiometer, making the process quick and efficient—usually taking just a few minutes. To calibrate, the sensor elements of the radiometer are placed in the mounting tray where the test sample is normally positioned. The data cable is connected to the calibration port on the front panel. Once the radiometer measures the lamp output and sends the signal to the control system, a single button press completes the calibration. This automated process eliminates human error in data entry and avoids the need to move the lamp or filter during the procedure, ensuring accuracy and convenience.

In contrast, the calibration of a water-cooled xenon lamp aging test chamber (rotary drum type) involves multiple steps and requires the use of a special calibration lamp. The process typically includes:

1. Removing most of the test samples from the chamber.
2. Disassembling the operating lamps and filters.
3. Installing a calibrated reference lamp.
4. Measuring the irradiance of the calibrated lamp and comparing it to a known standard value.
5. Adjusting the instrument settings to match the measured value with the calibrated value.
6. Removing the calibration lamp after the adjustment.
7. Reinstalling the original lamps and filters.
8. Reintroducing the test samples before restarting the exposure cycle.

This multi-step approach ensures that the irradiance levels remain consistent and accurate, which is crucial for reliable aging test results.
