HGM-SZ Halogen Gas Leak Monitor, Single Zone

The Bacharach HGMSZ (Halogen Gas Monitor Single Zone) is designed for continuous single-point monitoring of CFC, HFC, HCFC, and Halon refrigerant gases. The HGMSZ displays the type of gas being monitored, along with displaying both the current gas level and the peak gas level detected on its front panel LCD. The instrument retains a log of previous readings that can be easily accessed for analysis.

An internal audible alarm and front panel indicators are provided to signal alarm and fault conditions, and relay contacts can be used to trigger external alarm devices in the event of a system fault, or if a leak (small), spill (medium), or evacuation (large) level of gas is detected. The system also includes a 4-20 mA current loop interface that can be connected to remote monitoring equipment.

• Easily complies with ASHRAE 15 requirements with a low-cost investment
• Eliminate false alarms with use of non-dispersive IR source and sample draw system

• Three gas alarm levels that can be individually set
• Front Panel Indicators:
  • Monitor ON - green light ON when unit is operating normally, or flashing during warm-up
  • System Fault - Yellow light ON when there is a system fault
  • Alarm - Red light ON when the gas level is above an alarm setting
• Output Signals: 4 SPDT, 5 Amp, 240 VAC relays; digital display; and a 4?20 mA DC current loop output
• Bolt-in, bolt-out internal components so the unit never leaves the wall
