The GDS 303 system is designed to monitor gas levels from a large number of sample-points, targeted at situations where the positioning of conventional gas sensors may not be practical. This may be due to equipment security, cable routing, access for detector head installation/maintenance, harsh environment or a cost effective means of monitoring designated hazardous areas, typically - tunnels, underground/high level voids, process control, landfill, brewing, horticulture, livestock husbandry.

Gas samples are sequentially extracted for a timed period by a central control unit via fixed sample lines. A high rate sample is taken by the main pump during which a smaller pump passes a reduced rate sample across the sensor device.

The central unit provides gas level readouts with two alarm trip points per line, having alarm functions available for annunciator and control actions.
