The six secrets of the "long life" of the high and low temperature damp heat test chamber:
(1). High and low temperature damp heat test chamber check over temperature protector: When the high and low temperature damp heat alternating test chamber is running, the maximum value of over temperature protection is increased by 20 °C ~ 30 °C. When the temperature in the test box 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 [over temperature protector set to 120 ° C].
(2). Removal of dust from the condenser of the high and low temperature damp heat test chamber: The condenser should be regularly maintained monthly, and the dust attached to the condenser heat dissipation mesh may be sucked off by a vacuum cleaner or the dust may be sprayed off by high pressure air.
(3) High and low temperature damp heat test chamber humidifier inspection and maintenance: The water storage in the humidifier should be replaced once a month to ensure the water quality is clean, and the humidifying water pan should be cleaned once a month to ensure smooth water flow.
(4) Check and adjust the wet water level of the high and low temperature damp heat test chamber: the water level of the water trap should not be too high, so that the water overflows the water trap or the water is too low to make the wet bulb test cloth absorb water abnormally, affecting the accuracy of the wet bulb. It can be kept about six minutes. The water level of the water tank can be adjusted to adjust the level of the water tank.
(5). Exchange of high and low temperature damp heat test chamber wet ball test cloth: When the surface of the test cloth is not clean or hardened, or after the temperature control is completed, the test cloth must be replaced before continuing to do the temperature and humidity sphericity control. The test cloth should be replaced once every three months. When replacing the cloth, wipe the temperature measuring body with a cleaning cloth. When replacing the new test cloth, it should be cleaned first.
Since the high and low temperature damp heat test chamber is a charged product, it has certain dangers. Therefore, once the equipment is found to be faulty, for the sake of safety; the operator should remember not to disassemble or replace the parts at random, and should contact the original manufacturer for the first time to check the cause of the malfunction, so as to avoid unnecessary trouble.
