The MGS-150 Gas Detector can meet almost any gas detection need with multiple sensor options for real-time monitoring of refrigerants, oxygen, combustible and toxic gases. It includes user-selectable current or volt analog outputs, allowing connectivity to most BMS, SCADA or central control systems. Status LEDs and a buzzer are integrated for local alarming while an onboard relay with user-adjustable set-point can connect to external visual/audible alarms.

A variety of enclosure options, including an economical IP41 housing and a dust/water tight IP66 housing, allow the MGS-150 transmitters to be placed in the toughest environments. Special remote sensor configurations are available for applications where mounting in vent pipes, duct work or other tight spaces is required.

• Infrared, electrochemical and MOS sensor options
• Detects CFC, HCFC, HFC, refrigerants, oxygen, toxic and combustible gases
• Selectable current or volt analog output
• IP66 housing options, including remote and duct mount sensors
• Built-in relay with adjustable set-point
