    The temperature and humidity abnormality of the constant temperature and humidity culture box should deal with the temperature and humidity culture box has an accurate temperature and humidity control system, it provides the production research, biotechnology testing needs a variety of simulated environmental conditions, can be widely used in drugs, food processing and other sterile tests, stability checks and industrial products raw material performance, product packaging, product life and other tests.
    The temperature of the constant temperature and humidity culture box, humidity abnormal constant temperature constant humidity culture tank can be carried out high temperature, low temperature, humidity and other tests, the constant temperature and humidity machine in the course of the test a variety of temperature, humidity failure, can be handled according to the following methods: 1, the temperature of the constant temperature and humidity culture box can not reach the indicators set by the test need to observe whether the temperature changes, is the temperature drop is very slow, or the temperature after reaching a certain temperature value has a tendency to pick up.
    the former had to check the cause, whether the studio had been dried before doing the cryogenic test, and then the studio kept dry before putting the test samples in the work room for further testing.
    Then check whether the test samples in the studio are placed too much, so that the air in the studio can not be fully circulated, after excluding the above reasons, it is necessary to consider whether the culture box refrigeration system has failed, if so to ask the supplier's professional repair personnel for maintenance.
    The latter phenomenon is caused by the constant temperature and humidity culture tank in a bad environment, the temperature of the environment placed in the constant humidity culture box, the location (the distance between the back of the box and the wall) to meet the requirements (in the operating instructions of the equipment are specified).
    2, the high temperature of the constant temperature and humidity culture box does not meet the target set by the test If the temperature change of the culture box does not reach the temperature value required for the test, you can check the culture box heating electrical system, one by one troubleshooting.
    Thermostat constant humidity culture box If the temperature rises more slowly, you need to check the wind circulation system, see if the regulating bezel of the wind cycle is open normally, and conversely, check whether the motor of the wind cycle is running normally.
    if the temperature is too strong, then the SETTING parameters of the PID need to be fixed.
    if the temperature rises directly, over-temperature protection, then, is the culture box controller failure, must replace the control instrument.
