This series of products has an accurate temperature and humidity control system that provides the various environmental simulation conditions required for industrial research and biotechnology testing. Therefore, it can be widely applied to sterility tests such as medicine, textile, food processing, stability inspection, raw material properties of industrial products, product packaging, product life and other tests.
1. Independent humidification for humidity control
2. LCD multi data full screen display, power failure memory, power failure compensation
3. Convenient operation, constant value operation, regular operation and automatic stop
4. Special function key to realize temperature setting
5. Auxiliary menu, realize over rising alarm, deviation correction and menu locking
6. Forced air supply by centrifugal turbine makes the temperature more uniform
