WS433-G4 is a Sub-GHz electrochemical-type gas sensor with a high sensitivity to low concentrations of detected gas, high selectivity, and a stable baseline. The device supports different types of gas such as CO, NO, NO₂, H₂S, NH₃, O₂, O₃, SO₂, Cl₂, HCHO... Ultra-low Power design and smart firmware allow the sensor to last up to 5 years with a 02 x AA-type battery (depending on configuration). The sensor will transmit data at a hundred meters distance to the Wireless Coordinator WS433-CL. The coordinator will give output RS485 ModbusRTU to any SCADA or DCS system.
