GDS-58DXP Dual Channel Sample Draw for Toxic & Hydrocarbon Combustible Gases

Brand: GDS Corporation

Sample Draw Monitors are designed to be used when the sample location is not suitable for the installation of a fixed gas monitor.

This can include confined spaces, locations where maintenance is difficult or in areas where environmental conditions are unsuitable for the desired sensor.

The GDS-58DXP sample draw gas monitor is an ideal solution for ambient gas detection applications where the monitored location is unsuitable for the direct installation of a fixed gas detector due to enviromental, access or other reasons.

The GDS-58DXP sample draw monitor is designed to detect a wide range of toxic and combustible gases in potentially hazardous environments.

The monitor operates on +24 VDC volts DC and includes an optional 110/220VAC power supply.

Outputs include dual industry standard 4-20 mA analog signals as well as a MODBUS port.

Optional alarm relays allow the GASMAX DSX to communicate with a wide range of industry devices and system controllers.
