Due to long-term use of the constant temperature and humidity test box, some fine dust in the air will enter the box, and the more dust will accumulate with the increase of time, so that many problems will occur during the use of the test box. Therefore, in daily life, it is necessary to pay attention to maintenance equipment regularly, which can increase the service life of the test chamber.

3. When checking the operation of the over-temperature protector, set the maximum value of the over-temperature protection plus 20 ℃ ~ 30 ℃. When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply to the heater will stop, and the "OVERHEAT" over-temperature warning light will be on but the fan is still running. Whether the over-temperature protector is set properly (the setting of the wet bulb over-temperature protector is 120 ℃).
