1. The temperature and humidity control instrument adopts the "Korean original TEMI850" large screen - liquid crystal display - programmable microcomputer PID control SSR output operation. Fully imported large LCD touch screen, easy to operate on the screen, easy to program.

2. Accuracy: 0.1 ° C (display range).

3. Resolution: ±0.1 °C.

4, temperature sensor: PT100 platinum resistance temperature measuring body.

5. Control mode: heat balance temperature regulation and humidity control mode; all electrical appliances adopt (Schneider) series products.

6. Temperature and humidity control adopts P. I. D+S.S.R system coordinated control with the same channel.

7. With automatic calculation function, the temperature and humidity change conditions can be corrected immediately, so that the temperature and humidity control is more precise and stable.

8. The controller operation interface is available in Chinese and English, and the real-time running graph can be displayed on the screen.

9, with 100 sets of programs, each group of 100 segments, each segment can cycle 999 steps of capacity, each period set the maximum value of 99 hours and 59 minutes.

10. After inputting the data and test conditions, the controller has a screen lock function to avoid human touch and stop.

11, with RS-232 or RS-485 remote communication interface, can design programs on the computer, monitor the test process and perform automatic switching machine and other functions.

12. The controller has a screen automatic screen saver function to better protect the LCD screen during long-term operation (to make it last longer).

13. The air return port of the test chamber has an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator, causing ice blockage).
