Analysis and solution of the problem of constant humidity alarm in the constant temperature and humidity box

In the large family of incubators, the constant temperature and humidity box is a precision environmental test instrument that is used very frequently. Generally speaking, the constant temperature and humidity chamber is equipped with a refrigeration system, a temperature system, a humidity system, a sensor system, and a fan system. The systems cooperate with each other to strictly follow the settings of the test chamber and control it in a stable state. However, in the process of use, as the use time is extended, the equipment will experience different degrees of aging, and sometimes some failure problems will occur. At this time, we need to analyze and solve different failure responses. This article mainly introduces It is the problem analysis and solution of the constant temperature and humidity box humidity alarm.

Humidity Chamber

Because the constant temperature and humidity box is equipped with a temperature and humidity sensor, it can automatically detect the temperature and humidity environment in the cabinet and display it on the screen. When the temperature and humidity environment is abnormal, the constant temperature and humidity box will alarm to remind the operator to deal with it. During use, if the humidity alarm does not stop, the possible cause at this time is: due to the large temperature difference between the inside and outside of the box, the surface of the humidity sensor is condensed after the door is opened, causing the humidity of the humidity sensor to rise rapidly beyond the test range or set According to the specified humidity range. The solution is: air-dry the humidity sensor on the top of the box, or wait for a long time to automatically remove the condensation, and the alarm will be automatically eliminated; minimize the number of door openings.

If the analysis finds that it is not caused by the above problems, but caused by instrument failure or parts damage, then you need to contact professional technicians to deal with it. Do not disassemble and repair it by yourself to avoid irreversible damage to the equipment. The above is the problem analysis and solution of the constant humidity alarm of the constant temperature and humidity box. We provide a series of constant temperature and humidity box products with a variety of models and volumes, with strong technical advantages, stability and reliability.
