1. Environmental temperature: 5-28 ℃; (up to 30 ℃, but may affect some performance);

2. Environmental humidity:<85% R.H (25 ℃);

3. Atmospheric pressure: 86-106Kpa;

4. Environmental conditions: There is no strong vibration, strong electromagnetic field interference, high concentration dust and corrosive substances around the equipment site, and no direct sunlight or radiation from other heat sources.

5. The equipment should be placed horizontally in a well ventilated laboratory, with sufficient space around for operation and maintenance.

The programmable constant temperature and humidity testing machine is mainly used to test the performance of products during storage, transportation, and use in high and low temperature climate environments. It is mainly used to test the physical and other related properties of electrical and electronic products, components, parts, metal materials, and products under simulated high and low temperature climate conditions. After testing, the performance of the product can be judged through calibration to determine whether it can meet the requirements for product design, improvement, calibration, and factory inspection.
