Xenon arc aging tester calibration

Xenon lamp aging tester is the experimental equipment for laboratory accelerated weathering aging test of materials. Currently, most are imported. Our company Shanghai QINSUN Precision Electromechanical Technology Co., Ltd. is a manufacturer of textile testing instruments, which can produce individual models. The domestic aging machine can also act as an agent for imported brands. Welcome customers who need to inquire in time. In addition, Shanghai QINSUN technical engineer said that using xenon lamp aging test machine, irradiance calibration is very important. The user can entrust the calibration to the manufacturer or a measurement institution, or use the method provided by the manufacturer to self-calibrate. The methods of calibrating the irradiance of different manufacturers' aging test chambers are not the same, but the following two methods are commonly usedkt for calibration.

1. Calibrate with a standard lampMXUTextile Testing Instruments, Testing Equipment Manufacturer

There is a strict and accurate relationship between the power of the standard lamp and the irradiance, and the irradiance can be determined by the power of the standard lamp. When using standard light calibration, you must first remove the work light, install the standard light, then start the device to enter the corresponding mode, let it automatically calibrate according to the relationship between power and irradiance, and then remove the standard light, install Back to work lamps. The process of calibrating with standard lamps is complicated and cumbersome and requires specially trained personnel. If you are not careful, the xenon lamp can be damaged and even personal safety can be compromised. Because this method depends on the corresponding relationship between the power and irradiance of the standard lamp, and the corresponding relationship between the powern and the irradiance of the xenon lamp will change after aging, the service life of the standard lamp is relatively short, and the price is relatively high Increased user costs. Standard lamp calibration is common with water cooled xenon arc weathering testers. MXUTextile Testing Instruments, Testing Equipment Manufacturer

2. Calibrate with a radiometerMXUTextile Testing Instruments, Testing Equipment Manufacturer

Compared to standard lamps, calibration with a radiometer is simple, quick and intuitive . When calibrating, place the radiometer's sensor on the sample rack in the xenon lamp aging chamber, ensure that the light-receiving surface of the sensor faces the light source, and ensure that the distance from the light-receiving surface to the light source is consistent with the distance from the sample surface to the light source, and then compare the radiation Calibration can be performed with the measured value of the meter and the xenon lamp aging test chamber, such as the US Q

-Lab The xenon tester can even be calibrated automatically without human intervention. In this way, even personnel without special training can perform the operation. In addition, the price of the radiometer lower than that of the standard lamp, it can be used safely without frequent replacement, and it only needs to calibrate the radiometer regularly (usually one year).
