Gas Sensor with Modbus output MBRTU-G4

SKU: MBRTU-G4

Doc No: MBRTU-G4-DS-EN-10

Introduction

MBRTU-G4 is an 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, and HCHO...It is powered by a wide range of power supplies 7..48VDC and gives output via RS485 ModbusRTU.

High accuracy and stability;
Wide range of Power Supply;
Sintered metal filter to protect sensor;
Optional splash guard to protect the sensor from water injection;
Standard ModbusRTU output;
Plug & Play.

Typical Applications

Ambient Gas Monitoring in Facilities, Farm, Building, Factory, City...

Indoor Air Quality monitoring;
HVAC Control;
Greenhouse;
Smart Agriculture.
