Within the external temperature and humidity chamber varies by location, different face of the test environment, the pressure required is different, so maintenance is also different. So, what is the difference between the internal and external maintenance of the constant temperature and humidity test chamber? External maintenance of constant temperature and humidity chamber: 1, the outer box must also cleaned once a year or more, the first cleaning wipe with soapy water. 2, distribution chamber clean at least once a year or more, when using a vacuum cleaner dust sucked to the indoor. 3. The constant temperature and humidity test chamber should remove the internal impurities before operation. Constant temperature and humidity machine internal maintenance: 1. Check and maintenance of the humidifier of the constant temperature and humidity test chamber The water storage in the humidifier should be replaced once a month to ensure the water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow. 2 , constant temperature and humidity test chamber condenser dust removal condenser should be regularly maintained monthly, using a vacuum cleaner to absorb the dust attached to the condenser heat sink net or use high-pressure air to spray dust. 3. Constant temperature and humidity test chamber Check the over temperature protector When the constant temperature and humidity test chamber is running, the maximum value of the over temperature protection setting is increased by 20 °C ~ 30 °C. When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply of the heater will stop. The "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is running for a long time and unattended, please check it before running. Over temperature protector, is set properly [ wet ball over temperature protector is set to 120 °C ] . 4 , constant temperature and humidity test machine wet ball test cloth replacement When the test cloth surface is not clean or hard, or after the temperature control, continue to do the temperature and humidity sphericity control must be replaced before the test cloth. The test cloth should be replaced once every three months. When replacing, use a cleaning cloth to wipe the temperature measuring body [Sen-sor] . When replacing the new test cloth, it should be cleaned first. 5 , constant temperature and humidity test box wet ball water level check and adjustment water level can not be too high, so that the water overflows the water tank or too low so that the wet ball test cloth does not absorb water properly, affecting the accuracy of the wet ball water level is about six You can fill it up. The water level of the water reservoir can be adjusted to adjust the level of the water tank .
