The first is that users who use constant temperature and humidity chambers may encounter this situation. In the test session, the temperature suddenly shows that the temperature is full, but they do not know what is the cause?

Check whether the wet ball gauze is hanging on the temperature sensor. The sensor near the sink is the temperature sensor. The gauze should be hung on the temperature sensor and wrap the temperature-sensing part of the sensor. There are very few customers who often hang the gauze in the wrong place and hang it. On the top of the temperature sensor, the common failure of the machine is caused. Therefore, please distinguish carefully. The top one is the temperature probe, and the bottom one near the water tank is the temperature probe.

If the hanging method is accurate and the temperature still shows 100%, please check whether the wet ball gauze has turned yellow, or if the gauze has been used for too long, too many minerals have accumulated on the gauze, which will reduce the water absorption capacity of the wet ball gauze. Inability to absorb water, thus making the detected temperature inaccurate, resulting in the false image of high temperature;

If it is, please replace the wet ball gauze. If not, you need to check that there is no water in the wet ball tank or the water level is slightly low, and the gauze cannot absorb water. The key is to check the following parts to see if there is water in the water level box by the sink. , If not, it is possible that the float ball is damaged or the electromagnetic pump is damaged. Use the voltage range of the multimeter to measure its resistance. If it is open, it will be damaged.

There is also a problem of controller settings. There are very few customers who have a misconception about the application of constant temperature and humidity chambers. They often set the temperature at low temperature, and set the temperature when the high temperature is 120 degrees Celsius. This kind of situation will also cause control. The machine is inaccurate and unstable. The low temperature machine cannot control the temperature and is easy to freeze; the continuous high temperature evaporates too fast, and the setting of the machine for the temperature is also very difficult. Therefore, customers are requested to read the instructions carefully, operate the machine in a standardized manner, and extend the service life of the equipment
