EF-306 Sequential Gas Sampling System

Key Features
1-20 sample points
Monitor up to 4 gas types
No sample line purge delay
Wide range of sensor types
4 line alpha/numeric display

Overview

The 306 system is designed to monitor gas levels from a 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, marine applications, underground/high level voids, process control, landfill, multi storey car parks, brewing, horticulture, superstore multi refrigeration units.
