The Nova 510DR 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.

The 'DR' models are configured such that the oxygen sensor(s) are mounted outside of, and electrically connected to, the main cabinet (max distance between remote sensor & main cabinet - 50ft). This allows allows O2 monitoring of single or multiple remote zones, with centralized display and alarming features. The remote sensors are the diffusion type, with no pump or moving parts.

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:
  • 510DR1 - Control cabinet with one remote diffusion sensor
  • 510DR2 - Control cabinet with two remote diffusion sensors
  • 510DR3 - Control cabinet with three remote diffusion sensors
  • 510DR4 - Control cabinet with four remote diffusion sensors
