Nuvair PRO O2 Oxygen Analyzer (Panel Mount)


Accurate, stable, and easy to use, the panel mounted Nuvair Pro O2 Alarm Analyzer has two audible and visible alarms that can be set for high and low oxygen content. When the alarm sounds, the analog output activates an optional relay that shuts down compressor automatically, sounds a remote alarm, or switches a surface-supplied diver’s breathing gas to an emergency backup system. Designed for installation on a control panel or other flat surface, Nuvair Pro O2 Alarm analyzers are built and tested in-house and come ready to use. Designed for in-line measurement of oxygen in a mixed gas, it is compatible with nitrox, heliox, and trimix.
