GASMAX QSM Four-Channel Wired Gas Monitor
Brand: GDS CorporationThe GDS Corp GASMAX QSM quad-channel gas monitor supports up to four local or remote sensors for hazardous toxic or combustible gases or a wide range of dangerous volatile organic compounds (VOCs).
Sensors can be mounted locally or up to 50’ away using the Remote Sensor Kit.
The GASMAX QSM consists of four independent sensors and associated sensor electronics assemblies that can be configured for any GDS Corp sensor type.
Each sensor assembly has independent fault, analog 4-20mA and digital RS-485 serial outputs and two user-programmable alarm setpoints with front-panel LED alarm indicators.
The GASMAX QSM includes a standard top-mounted red, amber, blue or tri-color strobe and bottom-mounted dual-tone buzzer.
When configured for Remote Sensors, the GASMAX QSM ships with four remote sensor assemblies and cable and requires an external source of +24VDC.
