The Nova 510 Series oxygen deficiency or excess alarm monitors are designed as an O2 'watchdog' against accidental displacement of ambient air in a confined space by inert gases, or by a buildup of too much O2 from an O2 leak in the room. The monitors all utilize a long life electrochemical O2 sensor. Actual O2 concentration is shown on a digital meter on the front panel.

Optional dual level alarm with local indication, relay contacts, and audible alert available. Alarm set points are pre-set at Nova but are field adjustable if desired. Flashing strobe light and upgraded cabinets also available.



Models:
  • 510D - Diffusion sensor, no pump and no moving parts; excellent for O2 monitoring in immediate local environment
  • 510P - Pumped sample version; pump pulls air sample from wider area or from another isolated environment, such as from a closed room
