Constant temperature and humidity box temperature and humidity controller how to solve the abnormali


    How to solve the constant temperature and humidity chamber temperature and humidity controller? The constant temperature and humidity box belongs to Lab high precision instrument, and the size is large, and there is more inconvenient in moving. At the same time, its circuit system is complex. When it is faulty, the user often doesn't know where it is. The Shanghai Sheng Instrument Technical Experts mainly introduces the constant temperature and humidity changing temperature and humidity controller display temperature, how to determine the cause of the failure and make corresponding solutions. 1. The temperature and humidity controller of the constant temperature and humidity is abnormal. At this time, we must first check the overwescent protector of the control unit to see whether it is still 150 ° C. 2. Second, after checking the pipeline in the laboratory, it has not been cleaned for too long. 3, ZUI After checking the solid state relay of humidity, there is no short circuit. If there is no problem with the heater, then we can use the electricity to AC voltage file to detect.
    4, can also turn off the total power supply of the constant temperature and humidity box, open the drain valve below the heating tub to the position parallel to the pipeline, discharge the water inside, clean the internal dirt, then pull the silicone The pipeline is removed, washed in the water, and then put it back in the reverse direction after the maintenance is completed. After the device is completed, the drain valve below the humidification bucket needs to be closed to the vertical position perpendicular to the line, and then open the main power supply of the machine.
