Product Description

Product Description

 SEM223 transmitter adopts a new infrared verifcation technology to measure CO2 concentration. The response is quick and sensitive, avoiding the life and long-term drift of traditional electrochemical sensors. It is widely used in agricultural greenhouses, fower cultivation, edible fungus cultivation, etc. that require CO2 and temperature and humidity. Monitoring occasions. 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the farthest communication distance is 2000 meters. The equipment has 10-30V wide voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on site.
