How to choose a constant temperature and humidity test chamber

constant temperature and humidityTest chamberAlso known as constant temperature and humidity testing machine, constant temperature and humidity test box, programmable humidity and humidity alternating test box, constant temperature machine or constant temperature and humidity box, equipment used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. Suitable for electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products for quality testing.

First, size selection:

The general constant temperature and humidity size is determined according to the size of the test product

Second, the choice of voltage:

Constant temperature and humidity box power supply selection whether it is220VStill380VAre three-phase power interface, if the temperature in-40Below the degree, and the box is in.225LAbove, it is recommended to choose380VFour-phase power interface, because it is relatively stable for the entire laboratory, the life of the equipment itself is also good.;

3. air cooling and water cooling options:

The constant temperature and humidity box is generally air-cooled, and the water-cooled one is generally a large constant temperature and humidity room or a large box of rapid temperature rise and fall testing machine. Generally, the cold and heat shock test box is more water-cooled.;

4. constant temperature and humidity box use environment:

　　Environmental tests, especially reliability tests, have a long test cycle, and the test objects are sometimes military products of high value. During the test process, the test personnel often have to operate or test around the site. Therefore, environmental test equipment must have the characteristics of safe operation, convenient operation, reliable use and long working life to ensure the normal operation of the test itself. All kinds of protection, alarm measures and safety interlocking devices of test equipment should be perfect and reliable to ensure the safety and reliability of test personnel, tested products and test equipment itself.
