The temperature and humidity incubator appear slower, humidity fault, how to solve?

"
Pharmaceutical Network Technical Article" Constant temperature and humidity incubator with precise temperature and humidity control system, for biotechnology testing to provide the required various environmental model conditions, applicable to environmental protection, health and epidemic prevention, drug testing, agriculture and animals, aquaculture and other scientific research, institutions, production departmentsIn recent years, with the rapid development of the biopharmaceutical industry, more and more enterprises, institutions layout and upgrade laboratory equipment, for the constant temperature and humidity incubator and other equipment demand has also increasedreliable and stable equipment will support the testThe author learned that, at present, the domestic constant temperature and humidity incubator function complete, according to the needs of users to selectHowever, the user in the process of use, also do not avoid encountering some glitchesfor example, a few days ago, a user said that the constant temperature and humidity incubator in the course of the test, occasionally appear abnormal temperature, humidity situationWhat's going on here? And how to fix it? There is constant temperature and humidity incubator manufacturers technical personnel for humidity does not come down, humidity does not go up, low temperature does not go, high temperature does not come to the situation was analyzed, and give the corresponding solutionHumidity does not come down
in the wet and hot test, there is a real humidity of 100% or the actual humidity and the target humidity difference is very large, the value is much lowerFor the former, the industry believes that it may be because the gauze on the wet bulb sensor is too dry, need to check the wet bulb sensor in the sink water shortage, control the water level in the water level of the water controller water supply system is normal, water level controller is working normallyIt may also be due to the long use of wet gauze, or the purity of water supplyIt is characterized by a hardening of the gauze, which cannot absorb moisture and dryIn this case, it is recommended to replace or clean the gauze for the latter, may be because the humidification system does not work, users can check the water supply system, check whether there is a certain amount of water in the water supply system, check the control of the humidification boiler water level control is normal, humidifier boiler water level is normal Humidity does not rise
humidity does not rise because the humidification heating tube does not work At this point, it is necessary to check whether the heating tube is open, whether the heating circuit has a broken wire or a short circuit to burn the fuse In the case of a burned fuse, check the solid state relay for breakdown during service, and if the main circuit is NO problem, check the controller output for damage Low temperature does not for low temperature does not reach the test target, it is necessary to observe the temperature change If the temperature drop is very slow, it is necessary to check, do low temperature test before the studio to keep dry and then put the test sample into the work room to do the test, whether the test sample slot in the workshop too much cause the room wind can not fully circulate, after eliminating the above reasons, it is necessary to consider whether it is a refrigeration system fault if the temperature drops to a certain value after the trend of recovery, it is necessary to check whether the equipment is not the use of the environment caused by the equipment, the installation of the ambient temperature, placed placed (the distance from the box and the wall) need to meet the requirements High temperature does not come to in the high temperature test, the temperature change can not reach the test temperature value, you can check the electrical system, one by one to troubleshoot If the temperature rises very slowly, check to see if the regulatory bezel of the wind circulation system is switched on normally, and vice versa, check that the motor of the wind cycle is running properly If the temperature rises directly and the temperature is protected by overtemperature, the control gauge needs to be replaced.
