Maintenance skills of Temperature and humidity test chamber

1. The internal impurities of the temperature and humidity test chamber should be cleaned before operation. The outside of the cabinet and the power distribution room should be wiped with soapy water. The cleaning frequency should be cleaned at least once a year. If the temperature and humidity test chamber is not used for a long period of time, the equipment should be energized regularly for a period of not less than one hour.

2. The water stored in the humidifier should be kept clean. It is recommended to change the water once a month. Clean the humidifying plate once a month to ensure smooth water flow.

3. The condenser is cleaned of dust every month. One method is to use a vacuum cleaner to suck the dust attached to the condenser heat-dissipating mesh, and the other is to use high-pressure air to spray dust.

4. The wet bulb test cloth of the temperature and humidity test chamber should be replaced once in about three months. When replacing the new test cloth, it should be cleaned first. When replacing, wipe the temperature sensor with a cleaning towel. When do we need to change the test cloth? In one case, the surface of the test cloth is not clean or hard. The second case is, after the temperature control is completed, continue before the temperature and humidity sphericity control.

5. The wet bulb water level line of the temperature and humidity test chamber should not be too high, and the water level can be kept at about 6 minutes. The water level of the water reservoir can be adjusted by adjusting the height of the water tank. The water level needs to be checked after every 3 to 4 tests.

6. When the temperature and humidity test chamber is working, the temperature of the over temperature protector can be set to the highest value of 20 ° C ~ 30 ° C. When the temperature in the test chamber rises to the set point of the over-temperature protection, the heater stops supplying power, and the "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is operated for a long time and unattended, please be sure to check the over-temperature protector before operation, and set it properly [the wet bulb over-temperature protector can set the temperature to 120 °C].
