Bacharach Single Zone (tube) Ammonia Gas Monitor AGM-SZ

Bacharach Single Zone (tube) Ammonia Gas Monitor


The Bacharach AGM-SZ Series Single Zone(tube) Ammonia Gas Monitor is designed for single point monitoring of ammonia gas with a 1/4″ O.D. tube up to 50 ft (15.2 m) distance from measuring point to monitor. The unit features a digital display for local indication of current gas levels and peak value. Three adjustable alarm levels with relay output designate leak, spill, and evacuation concentrations. Gas alarms and system fault conditions are indicated by visual and audible alarms. The Model AGM-SZ provides a system fault relay output and a 4 to 20 mA output for integration with remote monitoring equipment or building management systems. The AGM-SZ Single Zone (tube) Ammonia Gas Monitor is designed to be used as part of a control system that helps to prevent the formation of a hazardous environment when properly installed and maintained.
