The RAD-0012 Oxygen Enrichment Safety Alarm protects workers around bulk liquid stored oxygen or where oxygen generators are used. This includes applications like steel manufacturing, welding and cutting, cryogenics, hospitals, diving tanks, underwater facilities and emergency air backup systems.

While breathing elevated oxygen levels (hyperoxia) are not immediately dangerous, physical symptoms can occur in as little as 6 minutes. An additional risk is that elevated oxygen levels in an enclosed area increase the risk of fire.

In addition to the alarm, 3 built-in relays and 4-20mA outputs can control an exhaust fan, send a signal to a PID controller, warn emergency first responders or an offsite monitoring company.

Installation is easy. Mount the sensor unit and remote display on the wall (up to 300 ft. away), plug it into a standard wall outlet, and it will begin monitoring the room oxygen level in seconds


  • Large display clearly indicates current oxygen level
  • The fast-responding sensor uses the latest oxygen sensing technology
  • Designed to ensure safety compliance in any state
  • The remote display can be up to 300 feet from the sensor unit
  • Reliable connection with a standard Ethernet cable (25 ft. included)
  • 3 relays automatically control fans to ventilate confined spaces
  • 4-20 mA outputs for remote monitoring
  • 88dB audible and visual alarms on both sensor unit and display
  • IP54 Enclosure - prevents water damage during wash-down
  • UL Listed for Compliance
