The K800 series fixed gas detector, with 2, 3 or 4 wires connection, 4-20 mA RS485 Modbus output, provides continuous detection and monitoring of gases..

The K500 Series Wall-mounted Gas Detector, made with imported high sensitivity sensors and an explosion-proof design, has a long service life.

The 2 or 3 or 4 wire, 4-20mA and RS485 MODBUS output K800 series fixed device provides continuous detection and monitoring of gases for a wide range of industrial environments.
The fixed gas detector adopts advanced catalytic gas sensor or electrochemical sensor, which can translate the gas concentration in the air to the digital signal output.
