Using high-sensitivity gas detection probe, the signal is stable and the precision is high. It has the characteristics of wide measurement range, good linearity, convenient use, convenient installation, and long transmission distance. Using new infrared verification technology to measure CO2 concentration, the response is fast and sensitive, avoiding the life and long-term drift of traditional electrochemical sensors. Widely used in agricultural greenhouses, flower cultivation, edible fungus cultivation, etc. that require CO2, temperature, and humidity. Monitoring occasions. With analog or 485 communication, standard communication protocol, communication address and baud rate can be set, the longest communication distance is 2000 meters. The equipment adopts wide voltage power supply, and the enclosure protection level is high, which can adapt to various harsh conditions on site., Manufacturer: XZXXZSZ
