No matter how good the equipment is when it fails, how to quickly determine the fault and keep the constant temperature and humidity machine in good working condition is not only the goal of equipment manufacturers, but also the requirements of users. Next, the editor of the constant temperature and humidity machine will explain the troubleshooting methods for the failure of the constant temperature and humidity machine, hoping to be helpful to everyone.

1. If the low temperature does not meet the test requirements, first observe the temperature change, whether the temperature drops slowly, or the temperature tends to rise after reaching a certain value. Before the low-temperature test, check whether the studio is baked dry, keep the studio dry, and then put the test sample into the studio to test again. Whether there are too many test samples in the workplace, so that the wind in the workplace cannot be sufficient. After eliminating the above reasons, you need to consider whether there is a failure in the refrigeration system. You can contact the after-sales service department of the equipment manufacturer.

2. In the damp and heat test, the actual working humidity will reach an upper limit or the actual environmental humidity of the enterprise may differ greatly from the target humidity, and the value will be much lower. The former may be caused by the dry gauze on the wet bulb sensor, so check the wet bulb. If there is no water in the sensor water tank, you need to ensure that the water supply system of the water level controller is normal. If the humidification system is working normally, check the water supply and confirm whether the water supply system has a certain amount of water, whether the water level control for controlling the water level of the humidification boiler is normal and whether the internal water level of the humidification boiler is normal Is it normal.

3. If the thermometer and hygrometer suddenly fail during the trial operation, the corresponding failure display and voice alarm will be displayed on the control device. You can ask professionals to quickly solve the problem to ensure that the test is carried out normally. Other phenomena will occur when using other environmental test equipment, so specific phenomena need to be analyzed and eliminated.

4. In the high temperature test of the constant temperature and humidity machine, if the temperature change does not reach the test temperature value, the electrical control system can be checked, and the faults can be checked one by one. If the temperature rises slowly, check the air circulation system to see if the air circulation regulating baffle is normally open, or the solid state relay is faulty and needs to be replaced.

The above four points are all about the troubleshooting methods of the constant temperature and humidity machine. Thank you for your understanding and support!
