Temperature and humidity test chamber maintenance:
1. Check and adjustment of wet bulb water level in constant temperature and humidity test chamber
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. The accuracy of the wet ball can be maintained at approximately 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. When replacing the new test cloth, clean it 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 dust from the condenser heatsink mesh or use high-pressure air to remove dust.
4. Cleaning and maintenance of the exterior 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.
5. Check 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.
