1.Especially designed for agriculture equipments such as greenhouses, food and vegetable storages. Real-time detecting CO2 level, temperature and humidity with the local programmable control.

2.Wall mounting, LCD display

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 used up to 15 years

6.Temperature setting range: 5~45;Humidity setting range: 595%RH

7.rovid three relays outputs to control a CO2  generator, a temperature device and a humidity devise or a ventilator. 

8.Special photosensitive sensor detection can make the working mode of the CO2 generator changeover automatically in day and night.
