GDS  GDS-58NRG/38-017-12/0

The GDS-58NRG sample draw system is designed to accurately measure gas levels in areas with limited accessibility or in situations where harsh environmental conditions make the installation of a standard diffusion sensor difficult or impossible. The GDS-58NRG combines a GASMAX II gas monitor, adjustable flow meter, low flow switch and long life diaphragm pump in a single convenient package.

The GASMAX II state-of-the-art gas monitor features a high contrast backlit display that shows real-time gas values and 30 minute trend date. Flashing LEDs draw immediate attention to alarm conditions, and a diffused red/green LED flow indicator shows flow status at a glance. An internal real-time clock and event log time-stamps calibration and alarm events for later review

Optional 3x alarm relays and serial MODBUS port are available in addition to standard 4-20mA output. Jumpers are provided that allow the low-flow warning to interrupt the 4-20mA loop for remote indication of flow fault.

The GDS-58NRG supports any GDS Corp e-chem, 4-20mA or bridge-type sensor for non-reactive gases (See GDS-58GP for reactive gases). An easy-to-use menu- driven operator interface eliminates all analog potentiometers and allows setup and calibration to be completed without hazardous area declassification.

An integrated Run / Calibrate valve and user prompted calibration procedure make routine maintenance and field ‘bump tests’ quick and easy.

The GDS-58NRG Sample Draw system is designed for installation and use in industrial applications and hazardous areas rated Class I, Div 1. Temperature- compensated sensors and industrial- quality components allow reliable operation and rapid response down to 0°C.

The GDS-58NRG is ideal for sampling toxic or combustible gases in:

• Sumps and enclosed areas
• Cabinets or storeroom with limited ventilation or airflow
• Air conditioning intake or exhaust plenums and ducts
• Boiler burners and ducting
