Bacharach HGM-MZ Halogen Multi-Zone Gas Leak Monitor
Description
Bacharach’s Multi-Zone Gas Leak Monitors offer superior performance, flexibility and functionality for low level continuous monitoring of refrigerant gases used in most commercial systems including: Chlorofluorocarbons (CFC), Hydro chlorofluorocarbons (HCFC), Hydro fluorocarbons (HFC), Ammonia (NH3) and Carbon Dioxide (CO2).
These state-of-the-art fixed gas monitors lead the industry in performance, integration capabilities, initial cost and cost of ownership. Capable of detecting more than 38 refrigerant gases, the Multi-Zone system is compliant with ASHRAE standard 15-2007, is ETL Energy Saving Listed, meets California Code Regulations for Refrigerant Monitors and is EN 14624 and CE certified.
Features
- Proprietary infrared sensing technology virtually eliminates false alarms and extends sensor life
- No calibration required
- Low detection limits enable leaks to be found early, reducing energy and refrigerant consumption
- Fastest sampling rate with the longest sampling distance in the industry at 1,200 feet
- Large Graphic LCD for easy set-up and real-time monitoring
