Haloguard III Photoacoustic Infrared, Multichannel, Multi-gas Detection and Notification Refrigerant Leak Detection and Monitoring Systems
 
The HALOGUARD ® III combines advanced microprocessor based digital signal processing and a wideband photoacoustic infrared cell to provide the newest most advanced system for continuous monitoring of all refrigerant gases.
 
The HALOGUARD ® III monitors single or multiple, local and remote locations and provides notification when gas concentration reaches preset alarm levels. Up to 24 different gases may be monitored simultaneously 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.
