MSA - Model HGM-SZ -Single-Zone Refrigerant Monitor
Precision monitoring for low-level refrigerant leak detection for small to medium size facilities. The HGM-SZ Single Zone (tube) Refrigerant Gas Monitor is designed for continuous monitoring of CFC, HFC, and HCFC refrigerants and halogen gases with a 1/4 in. O.D. tube up to 50 ft (15m) distance from measuring point to monitor. Three adjustable alarm levels with relay output designate leak, spill, and evacuation concentrations. Gas alarms and system fault conditions are indicated by visual and audible alarms. The Model HGM-SZ provides a system fault relay output and a 4 to 20 mA output for integration with remote monitoring equipment or building management systems.The HGM-SZ Single Zone (tube) Refrigerant Gas Monitor is designed to be used as part of a control system that helps to prevent the formation of a hazardous environment when properly installed and maintained.
- Proprietary infrared (NDIR) sensor accurately detects the presence of a target gas down to an industry-leading 1 ppm Minimum Detection Level (MDL)
- Sensor is not prone to false alarms caused by cross-interference from other gases or sudden changes in temperature or humidity
- Gas library contains 50+ refrigerants, with Halogen, CO2 and NH3 versions available
- Backlit display shows real-time concentration readings and makes configuration and self-diagnostics intuitive
- High performance sampling pump for fast response times, including extending sample lines
