NV Series, Multi-Point Gas Detection System for Comb Gas

The NV-Series system is a Multi-point Single gas detection system that is available in 2, 4, 6, 8, 10 & 12 channel systems. The NV Series features a wall or panel mounted Indicator/Alarm unit and diffusion or suction type Gas Detector Heads.

The Indicator/Alarm unit comes with a direct reading LCD display (with backlight) and supplies power to the gas detector heads. 2-stage voltage and digital outputs are also obtained from the panel to connection to external devices / supervisory systems. The panel has dual-alarm levels with audible and visual alarms.

The Detector Head chosen will depend on the monitored gas as well as application (diffusion or suction). There is a wide range of detector heads to choose from.
