Small constant temperature and humidity experimental chamber

The small constant temperature and humidity experimental chamber has successfully passed the acceptance inspection of Sichuan High tech Rail Transit Industry Technology Research Institute

Usage of constant temperature and humidity test chamber:

The Haoen series high and low temperature humid heat test chamber provides temperature and humidity environment testing for parts, main accessories, and semi-finished products in various industries such as electronic components, automotive parts, and laptops. The constant temperature and humidity machine is mainly composed of a control panel, a distribution panel, a moisturizing compartment, a supply fan, a heater, and a refrigeration system.

Product Features:

1Design of the design: Arc shaped and surface spray treated, with a high-quality appearance, and using a flat non reactive handle, easy to operate, safe and reliable.

2Bright and wide field of view large observation window: using three-layer vacuum coating window and Philips energy-saving fluorescent lamp, no need for wiper defogging, maintaining clear observation effect, and allowing observation of the condition of the test sample at any time.

3Separation of humidification system pipeline and control circuit: The humidification system pipeline is separated from the power supply, controller, and circuit board to avoid affecting the circuit due to pipeline leakage and improve safety.

4Advanced and reliable refrigeration and control system: * European and American fully enclosed compressors, imported environmentally friendly refrigerants, refrigeration components, * LCD touch screen controller, user-friendly interface, easy to operate and learn.
