Constant temperature and humidity test chamber is a kind of commonly used experimental instrument, which has certain application in many industries. During the process of using the constant temperature and humidity test chamber, we should maintain and maintain the constant temperature and humidity test chamber for the longer life of the constant temperature and humidity test chamber.
1. Cleaning and maintenance of the outside of the constant temperature and humidity test box The constant temperature and humidity test chamber should remove internal impurities before operation. The power distribution room should be cleaned at least once a year or more. When cleaning, vacuum cleaners can be used to suck the room dust. The exterior of the cabinet must also be cleaned more than once a year. Wipe with soapy water before cleaning.
2. Check and maintenance of the humidifier in the 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.
3. Temperature and Humidity Test Box When checking the operation of the over-temperature protector's constant temperature and humidity test box, the maximum value of the over-temperature protection is set to 20°C~30°C. When the temperature in the test chamber rises to the set point of the over-temperature protection, the power supply to the heater stops. "OVERHEAT" warning light is on but the fan is still running. If it is running for a long time and is left unattended, please check before operation. Over-temperature protector is set properly [Wet ball over-temperature protector setting is 120°C].
4. Constant Temperature and Humidity Test Chamber Condenser Dust Removal The condenser shall be maintained on a regular monthly basis, using a vacuum cleaner to suck dust from the condenser heatsink mesh or use high pressure air to remove dust.
5. Check and adjust the water level of the wet bulb in the constant temperature and humidity test box. The water level of the water collection tube should not be too high, so that the water overflows the water collection tube or is too low to cause the wet ball test cloth to absorb water abnormally, affecting the accuracy of the wet ball. It can be full. Adjust the water level of the stagnant water tank to adjust the height of the water tank.
6. Replacement of the wet bulb test cloth in the constant temperature and humidity test box 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 the temperature and humidity sphericity control. The test cloth is replaced about three months. When replacing the cloth, wipe the temperature measuring body with a cleaning cloth and replace the new test cloth before cleaning.
In today's demand for industrial equipment, the use of test instruments has increased. We must pay attention to some problems when using them. To make these devices safer to use, I would suggest that some manufacturers should attach some instruments when selling some test equipment. Instructions and later maintenance and maintenance. Better service life of test equipment.
