The chamber temperature and chamber humidity of Q-SUN XE-2 and Q-SUN XE-3 share one sensor, also called a temperature and humidity sensor. The sensor adopts a non-calibration design. After one year of use, the readings of temperature and humidity will deteriorate and affect the test data. Therefore, when the device displays an M90 prompt, the sensor needs to be replaced with a new one (equipped with a calibration certificate).

The temperature and humidity sensor is shown in the following figure:
