Description
GT-WD2200 is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD screen and can be connected to the control panel with a standard 4-20mA analog output or RS485 digital communication.
Features:
Smart sensor module design, easy for replacement
Built-in buzzer and flasher
GT-WD2200 measures the concentration of the flammable gas, toxic gas, oxygen and VOCs
Explosion proof structure
Water and dust proof design
LCD screen display
IR remote control for setting and calibration.
Application:
Steelworks, Petrochemical plants, Shipyards, Water treatment plants, Mines, Power plants, Food industry etc.
