Monitors up to 16 remote areas, expandable to 48 points
Proprietary Infrared (NDIR) sensing technology
Low detection limits (as low as 1 ppm)
Long sampling distances (up to 1,200 ft / 365 m)
On-board visual/audible alarms, 4 relay contacts mitigates refrigerant loss

Description

Bacharach's Multi-Zone gas monitor offers superior performance, flexibility and functionality for low level continuous monitoring of refrigerants, carbon dioxide and ammonia. The 10 inch / 250 mm infrared sensor enables the Multi-Zone to accurately measure lowest ppm levels. A built-in library of over 50 gases and the scalability of the number of zones facilitate customization of the system. The large graphic LCD display and status LEDs provide a system-wide overview at one glimpse.

The Multi-Zone is a robust leak detector that offers effective refrigerant management. The sooner a loss of refrigerant is detected, the earlier countermeasures can be initiated, resulting in smaller recharge quantities of refrigerants. With the on-board relays and the optional Remote Display, the Multi-Zone fulfills the regulatory requirements as a refrigerant detection system. Using the Modbus interface or analog output, the monitor can be integrated into any BMS/BAS system.
