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.
Features & Benefits |
