The RAD-0002-ZR Oxygen Depletion Alarm is a room oxygen monitor designed to protect personnel against oxygen deficiency indoors near stored gases, such as nitrogen, argon, helium, nitrous oxide, or any inert gas. It can also be used in walk-in refrigerators or freezers with temperatures as low as -58°F (-50°C).

Our Oxygen Depletion Alarm uses an accurate, long-life sensor that requires no calibration and is maintenance-free for over 10 years. The 25% oxygen sensor can also be used as an oxygen enrichment alarm to detect when too much or too little oxygen is present.

Features

  • Real-time oxygen level readout on both sensor and remote display
  • Audible and flashing alarm on both sensor and remote display
  • Easy installation with no maintenance required
  • 3 user-configurable alarms that comply with all OSHA codes
  • Up to 3 remote displays can be daisy-chained and mounted up to 300 feet away
  • 4-20mA analog and relay outputs that can be used to control fans or off-site alarms

Benefits

  • Provides 24/7 protection for you and your staff against potential oxygen deficiency
  • Easy to install and use - simply wall-mount the sensor unit and remote display (all cables and hardware included), plug it into a standard wall outlet, and the alarm is ready to protect you and your staff
