1. The power supply equipment and the power supply line should be equipped with an overload fuse device, which has a special and good grounding device for the chamber. 2. Sample preparation. After numbering the samples one by one, place them on the turntable, and try not to touch or collide...
1. The input power supply voltage is too low. If only the allowed working voltage is low, the compressor current will be too large. 2. Repair the short circuit between the compressor turns, but it did not reach the level of cutting off the fuse. 3. Repair the secondary friction...
1. Open the side cover of the control chamber and check whether the setting value of the gas switch is correct, usually 50-80 degrees higher than the higher temperature of the machine. 2. The wind wheel of the constant temperature and humidity testing machine is not running, and the heat...
1. Temperature scale: Normally, the temperature of the constant temperature and humidity chamber is between -70-180℃. If some users need high temperature to reach higher or lower temperature, the price of constant temperature and humidity test chamber will be higher. The higher the technical...
1. When purchasing a constant temperature and humidity test chamber, first determine the size of the test chamber. The constant temperature and humidity test room does not fill the room like a refrigerator. The sample placed in the chamber should be separated from the inner wall to ensure air circulation around...

1. Exclude the remaining water in the water storage tank from the chamber, not only to avoid the dirt in the chamber from causing errors in the next test, but also to effectively maintain the tank and extend its life. 2. Remove the wet ball gauze in the studio. If the gauze turns yellow and...
1. thermal shock test chamber Inhibit the generation of static electricity: Since the source of static electricity is friction or separation between objects, it is necessary to suppress these functions as much as possible. For example, it is a good way to reduce the speed in operations such as liquid pipeline...
1. Install the temperature measurement sensor in the specified position, and adjust the temperature controllers of the high temperature chamber and the low temperature chamber to the required standard temperature respectively. 2. Respectively increase the temperature of the...
Installing a damping spring and a damping rubber pad at the bottom of the compressor of the high and low temperature test chamber can reduce the vibration transmission between the compressor and the base. The exhaust pipe of the compressor can use a metal shock-absorbing hose, which uses its...
high and low temperature test chamber After the test sample is put into the chamber, the channel will become narrower, which will increase the airflow speed and accelerate the heat exchange between the airflow and the tested product. This is inconsistent with the reproduction of environmental conditions,...
