■ Product features
1. High texture appearance, the body adopts a curved shape, the surface is treated with fog noodle pattern, and the plane without reaction handle is adopted, easy to operate, safe and reliable.
2. The rectangular double-layer glass observation window can be used for the observation of test products during the test. The window is equipped with a sweat-proof electric heater to prevent water condensation and droplets, and a high-brightness PL fluorescent lamp to maintain the lighting inside the box.
3. The double-layer isolation air tightness of the box door can effectively isolate the internal temperature leakage.
4. It has an external water supply system, which is convenient for replenishing the water supply of the humidification tank and automatically recycling it.
5. The compressor circulation system adopts the French "Taikang" brand, which can effectively remove the lubricating oil between the condenser tube and the capillary tube, and the whole series adopts environmentally friendly refrigerants (R23, R404) o
6. The controller adopts imported LCD display screen, which can display the measurement value, set value and time at the same time.
7. The controller has multi-segment program editing and temperature and humidity can be controlled by fast (OUICK) or slope (SLOP).
8.the built-in moving pulley is easy to move and place, and has a strong positioning screw to fix the position.
