The Remote Oxygen Enrichment Safety Alarm is designed to protect customers and workers near stored oxygen. High oxygen alarms are critical in cryogenics, cryotherapy, food production facilities, process cooling, or in any enclosed space where inert gases are stored

  • Wired O2 Monitor & Remote Display
  • Measures O2 concentrations from 20.1% to 25%
  • User configurable for specific applications

The Monitor has both audible and visual alarms. 3 built-in relays are triggered at 23%, 24% and 25% respectively that can control an exhaust fan or send an alarm to the fire department or monitoring company. The alarm levels are user-configurable to allow for specific applications

The Oxygen Storage Safety Alarm is easy to install and use. Simply mount both units on the wall (all cables and hardware included), plug the monitoring unit into a standard wall outlet, and the alarms are ready to protect your customers and employees
