The Remote CO2 + Oxygen Storage Safety Three Alarm is designed to protect people who work near carbon dioxide stored in tanks, closets or confined spaces, or who work with compressed nitrogen and run the risk of oxygen depletion in enclosed areas.

  • Wired CO2 + Oxygen Monitor & Remote Sensor
  • 3 Audible & Visible CO2 Alarms w. Relays

CO2 alarms are critical anywhere CO2 is stored or produced in high volume. The addition of an oxygen depletion alarm also makes this device critical for cryogenic, medical and industrial applications where nitrogen is stored. Like CO2, a nitrogen leaks in enclosed areas can quickly lead to asphyxiation. By monitoring oxygen levels, nitrogen leaks can be found.

The Remote CO2 + Oxygen Storage Safety Alarm has both audible alarm and flashing visual indicators when CO2 concentrations reach a pre-set level, or when oxygen drops below a pre-set level. Built-in relays can be used to control a ventilation fan, an HVAC control alarm, and to notify maintenance staff off-site when the PEL (Personal Exposure Limit) is exceeded. Learn more about room size coverage area.

The Remote CO2 + Oxygen Storage Safety Alarm is easy to install and use. Watch the installation video. Simply mount both units on the wall (all cables and hardware included), plug the display unit into a standard wall jack, and the alarm is ready to protect you and your staff.

Remote CO2 + Oxygen Storage Safety 3 Alarm

so far I am very pleased.

I have not managed to mount it in the submarine yet. Will it work as I want, then this will be great.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
