Constant humidity and heat test for security equipment

Constant temperature and humidity testing can simulate high temperature, low temperature, and hot and humid environments to conduct temperature and humidity tests on the test product in a specific environment, ensuring that the product being tested is under the same temperature and humidity environment. The constant humidity and heat test of safety protection and alarm equipment can test various performance indicators of the device and its adaptability in a hot and humid environment.
The Zhongke Testing Environmental Reliability Experiment Center has various environmental testing equipment for security alarm equipment and has constant humidity and heat testing capabilities. It provides professional constant humidity and heat testing services for intrusion alarm systems, video surveillance systems, remote receiving and monitoring centers and other equipment.

temperature, relative humidity, duration

Constant humidity and heat test (working state): Test the ability of the equipment to operate normally in an environment where short-term high relative humidity may occur and there is no moisture condensation.
Constant heat and humidity test (durability): Tests the ability of the equipment to withstand long-term humidity effects in the use environment (for example: changes in electrical properties caused by chemical reactions such as moisture, galvanic corrosion, or adsorption).

Constant heat and humidity test (working state): Place the test sample in an environment with constant temperature and high relative humidity. During the test, condensation on the surface of the test sample should be avoided. The length of time that the test sample is exposed to the hot and humid environment is selected based on the criteria of allowing water mist adsorption on the surface (but not condensation).
Constant heat and humidity test (durability): Place the test sample in an environment with constant temperature and high relative humidity. During the test, condensation on the surface of the test sample should be avoided. Exposure time is chosen to allow for moisture uptake and chemical changes to occur.
