Gas Transmitter CD-700 CO2
Gas Transmitter CO2
The CD-700 Gas Transmitter CO2 is a versatile device, available with over 10 types of gas and dust sensors. Also measures temperature, and humidity levels. It offers the added functionality of controlling ventilation and temperature through two relays. For enhanced convenience, the transmitter supports various output options such as RS-485Modbus communication and analog voltage/current 4/20ma.
more than 10 types of environmental gas and dust sensors. (CxHy, CO2, H2S, NH3, NO2, NO, SO2, H2, O3, PM, etc.)
Its convenience lies in its ability to measure, manage, and control complex gases by seamlessly integrating various types of sensors within the standardized CD-700 format.
