AGMSZ
The Bacharach
®
AGMSZ (Ammonia Gas Monitor Single
Zone) is an infrared detector based unit designed for
continuous single-point monitoring of ammonia gas. The
unit displays both the current and peak gas levels. Gas
alarms and fault conditions are indicated by audible and
visual alarms. The AGMSZ’s four relay contacts enable
external devices to be triggered when gas alarms or fault
conditions occur. A 4-20mA output enables the unit to
be integrated with remote monitoring equipment or
building management systems.
FEATURES
• Small in size, big in value
• False alarms are virtually eliminated with the use of
infrared detection technology
• Three gas alarm levels can be individually set by
the user
• Logging feature enables 200 gas readings to be stored
at user-selectable time intervals
• Two year warranty
