FIXED SYSTEM: GDS 301 Single line sample unit

GDS301 gas detection control panel

The GDS 301 system is designed to monitor gas levels in 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, marine applications, underground/high level voids, process control, brewing, horticulture, livestock husbandry.
