Product Features
1. Material quality of inner box is SUS304 # mirror-face stainless steel imported, and outer box is steel plate and the paint. Box body is processed shape using CNC machine tool, its shape is beautiful and fine.
2. Heat preservation material used glass fiber cotton of high-intensity PU foam and high density, which can avoid unnecessary energy loss.
3. Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design, built-in lights to facilitate the test sample state of real-time observation in the course of testing.
4. Large-size LCD display screen, simple operation, easy to edit programs. PID with automatic calculation function, show failure message .
5. An RS-232 communication interface, matching recorder, strong expandability.
6. with timing contact, and be able to cope with dynamic testing and measure test.
7. The system-wide multi-security protection and power-cut memory.
8. Freezer imported by the French original armored warrior compressor and use environmental-friendly refrigerant (R134a, R404a, R23).
9. Frozen system uses units or low-temperature dual-loop system design.
10. Use more powerful wing-blower air supply cycle, to avoid any dead end, temperature and humidity are evenly distributed in the test region.
11. Wind-road cycle adopted the design of blowing side wind and return wind. Wind pressure and wind speed are in accord with test standards, and make the door instantaneous temperature and humidity open that is stabilized time soon.
12. Heating, cooling, humidification and dehumidification system is totally unaided to improve efficiency, reduce testing cost, increase life expectancy and lower failure rate.
