Features: 1). Especially designed for agriculture equipments such as greenhouse, food and vegetable storage. Real time detects CO2 concentration, temperature and humidity with programmable logical control.

2). Compositive design and convenient connection with a handsome housing.

3). Carbon dioxide sensor, temperature sensor and humidity sensor are internal, the three values can be apart set

 4). Non-Dispersive Infrared Detector (NDIR) CO2 sensor, 15 years lifetime, CO2 setting range is selectable: 0~2000ppm / 0~20000ppm / 0~50000ppm

5). Special ABC Logic with patented Self Calibration Algorithm makes the CO2 sensor is used up to 15 years without calibration amending

6). Providing two or three relays outputs to control CO2 generator and a ventilator, or control CO2, temperature, humidity

7). Specially design for locale mounting with combine 16amp outlet loads

 8). Brightness detection makes CO2 generator changeover working mode automatically

 9). Large LCD with blue backlight displays the working status RS-485 communication interface with 15KV antistatic protection makes the controller can be connected with PC Strong functions& High performance with Low price
