Single-Zone Refrigerant Loss Monitor
SenTech IR-SNIF-1,2,3 provides compliance with ASHRAE Standard 15. It is based on an infrared technology that can detect multiple refrigerant types at concentration levels as low as 10 ppm. It detects all halogen-based refrigerants, and the refrigerant type can be field-changed without recalibration. Other features include a continuous digital display of system status; analog output for remote monitoring; system malfunction detection and indication; and visual alarm indication.
