The RAD-0002-ZR Oxygen Depletion Alarm protects staff against oxygen deficiency near stored gases and in walk-in refrigerators or freezers with temperatures as low as -58°F (-50°C).
Use it to monitor oxygen levels near storage tanks or cylinders of nitrogen, argon, ammonia, chlorine, propane, nitrous oxide, helium, argon or any inert gas.
The Oxygen Depletion Alarm uses an accurate, long-life sensor that requires no calibration and is maintenance free for 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 sensor and remote display
Audible and flashing alarm on sensor and remote display
Easy to install, no maintenance required
3 user-configurable alarms meet 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 to control fans or off-site alarms
10+ year sensor expected lifespan
The oxygen depletion alarm is easy to install and use. Watch the installation video. Simply wall-mount the sensor unit and remote display (all cables and hardware included), plug into a standard wall outlet, and the alarm is ready to protect you and your staff from potential oxygen deficiency 24/7.
Add-On Options
RAD-0022: Add-on Remote Display for RAD-0002-ZR Oxygen Depletion Safety Alarm above. Order up to 2 additional add-on displays to cover 3 entrances. Uses industry standard RJ45 Ethernet cable (not included) to install up to 300 feet away.
CM-1027: Dual Strobe Add On Kit. Flashing strobes plug into both the sensor and remote display to give a more visual alarm. Used in high-noise environments or where required by an inspector.
Certificate of Calibration - Available on request in comments at purchase.
