Haloguard IR Refrigerant Leak Detector Monitoring System

Overview

Photoacoustic Infrared, Highly Selective, Most Sensitive (1ppm), 24-hour Refrigerant Leak Detection and Notification Refrigerant Leak Detection and Monitoring Systems

The HALOGUARD ® IR combines advanced microprocessor based digital signal processing and a highly selective and sensitive photo acoustic infrared cell to provide the newest, most sensitive system for continuous monitoring of any refrigerant gas.

The HALOGUARD ® IR monitors single or multiple, local and remote locations and provides notification when gas concentration reaches preset alarm levels. Add individual, simultaneous monitoring of up to 3 different gases and up to 24 sample points by adding optional channel scanners and remote IR modules.

Alarm relays and analogue outputs are designed to activate remote devices or to interface with an energy management (EMS) or building automation (BAS) system.
