The high and low temperature test chamber is suitable for the cold resistance test and the adaptability test under the conditions of rapid temperature change or gradual change of the complete machine and parts of electrical and electronic products. Particularly suitable for conducting environmental stress screening (ESS) tests for electrical and electronic products. The equipment is mainly aimed at the adaptability test of electrical, electronic products, and their original devices, and other materials when stored, transported, and used under the environment of high temperature and low temperature rapid change. The test equipment is mainly used to simulate the physical and other relevant characteristics of the product under low temperature, high temperature and conditions according to national standards or user-defined requirements. After the test, the performance of the product is judged by inspection. Whether it can still meet the predetermined requirements for product design, improvement, identification and inspection by the testing plant.
The thermostat is used to test various materials (such as: sub, electrical appliances, communications, meters, vehicles, plastic products, metals, food, chemistry, building materials, medical, aerospace, etc.) heat, cold, dry, and moisture resistance device of. This is basically the same as the function of the high and low temperature wet heat box, but the constant temperature box does not do low temperatures below 0 Â° C, only constant tests.
From their use, it can be known that the high and low temperature test chamber is only used for high temperature and low temperature and not for humidity. If you want to do high temperature, low temperature and humidity at the same time, it is the high and low temperature alternating test chamber, constant temperature and humidity test chamber, etc. that circulate. The general constant temperature and humidity test chamber can do the humid heat alternating test, but it depends on the alternating test conditions of your atmosphere. If you want to purchase equipment, you should inform the supplier of your requirements before purchasing the equipment. So that the equipment can be designed and debugged according to your requirements. Of course, according to the conditions you mentioned, the manufacturer's price will be different.
Judging from their test temperature, the thermostat generally refers to the temperature of 15 degrees to 85 degrees, and the humidity can be 20% to 98% RH. Of course, lower humidity can be done according to the requirements. We call it the low temperature and low humidity test chamber. Then, the difference between the price of the high and low temperature test box and the price of the thermostat is that the thermostat does not perform low temperatures below 0 Â° C, only constant tests. But the high and low temperature test box does.
