How to maintain the temperature and humidity test chamber

1. Check and adjust the wet bulb water level in the constant temperature and humidity test box
The water level of the stagnant water tank should not be too high, so that the water overflows the water collection tube or is too low to allow the wet ball test cloth to absorb water abnormally. This will affect the accuracy of the wet ball. The water level should be maintained at about six full minutes. Adjust the water level of the stagnant water tank to adjust the height of the water tank. Almost every two or three trials need to be checked, and add water.
2. Change of wet bulb test cloth in constant temperature and humidity test box
When the surface of the test cloth is not clean or hardened, or after the temperature control is finished, the test cloth must be replaced before continuing the temperature and humidity sphericity control. The test cloth is replaced about three months. When replacing, wipe the temperature measuring body with a cleaning cloth [that is, the temperature sensor], and clean the new test cloth first.
3 constant temperature and humidity test chamber condenser dust removal
The condenser should be maintained on a regular monthly basis. Vacuum cleaners should be used to suck the dust attached to the condenser cooling mesh or use high-pressure air to remove dust.
4 temperature and humidity test box to check the over-temperature protector
When the constant temperature and humidity test box is running, the overheat protection setting zui high value plus 20 °C ~ 30 °C. When the temperature in the test chamber rises to the set point of the over-temperature protection, the heater power supply is stopped. The "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is operated for a long time and left unattended, it must be checked before operation. Over-temperature protector is set properly [Wet ball over-temperature protector setting is 120°C].
5. Cleaning and maintenance of the outside of the constant temperature and humidity test box
1) The internal impurities shall be removed before the operation of the constant temperature and humidity test chamber.
2) The power distribution room should be cleaned at least once a year or more. When cleaning, vacuum cleaners can be used to suck indoor dust.
3) The exterior of the cabinet must also be cleaned more than once a year. Wipe with soap and water before cleaning.
6. Inspection and maintenance of humidifier in constant temperature and humidity test chamber
The water storage in the humidifier should be replaced once a month to ensure that the water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow. Nowadays, many laboratories use pure water, but it is still very simple to clean the relevant cups every month.
