The reference standards are: GB/T2423.1-2008 Test A Low Temperature Test Method, GB/T2423.2-2008 Test B High Temperature Test Method, GB/T2423.3-2006 Test Ca Constant Damp Heat Test Method, GB/T2423.4-2008 Test Db Alternating Damp Heat Test Method
Laboratory decoration: strict insulation and moisture insulation performance is required. It is recommended to use color steel composite panels for the four facades of the laboratory, and PE insulation panels for insulation and moisture insulation treatment for the top and bottom surfaces; For perspective windows, it is required to use double-layer vacuum glass windows.
The controller operation interface is available in both Chinese and English, and the real-time operation curve chart can be displayed on the screen.
It has a capacity of 120 sets of programs, 12000 segments, and 999 loop steps, with a maximum time setting of 99 hours and 59 minutes per segment.
After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown.
It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.
Freezing and air circulation system.
The refrigeration unit adopts the original French "Taikang" fully enclosed compressor.
The refrigeration system adopts a unit or binary low-temperature circuit system design.
Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.
