In stock
Quick Overview

The Remote Oxygen Depletion Safety Alarm (CFX-C2M-RAD-0002) is designed to protect customers and workers near stored inert gases like Nitrogen, Argon, and others.

Low 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 0-25%
  • Mounted 60-72 inches from floor height
  • User-configurable for specific applications
  • UL Listed for Compliance


The Monitor has both audible and visual alarms. 3 built-in relays are triggered at 19%, 17%, and 15% 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 Depletion 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.
