Brief Introduction

● Simultaneous detection of single gas or two gases in air ducts

● High-precision electrochemical gas sensors with built-in temperature compensation, humidity detection is optional

● Built-in a sampling fan for stable air flow, 50% faster response time

● RS485 interface with Modbus RTU protocol or BACNet MS/TP protocol

● One or two 0-10V/ 4-20mA analog linear outputs

● Sensor probe is replaceable, supporting both inline and split mounting.

● A waterproof breathable membrane built in the sensor probe, making it suitable for more applications

● 24VDC power supply
