The Oxygen Sensor for Multi Gas Safety System is designed to ensure gas safety and monitor oxygen levels down to -50°C across a variety of industry applications. This sensor integrates with our Multi Gas Safety System. 

It uses advanced zirconia sensing to monitor and detect leaks of high concentrations, protecting staff when working near nitrogen, argon, helium and other gases.


  • Monitor oxygen levels down to -50°C with real-time oxygen level readout
  • Monitor CO2 and O2 on the same system (eliminate multiple controls on a single system)
  • Audible and visual alarms to protect staff near potential hazards
  • 3 user-configurable alarms (default is set at OSHA code)
  • The remote display can be mounted up to 300 feet away
  • Easy to install, uses standard RJ45 and CAT-5e/CAT6 cables
  • International Power Supply (included)
  • 10+ years of sensor life

Per both the Occupational Safety and Health Administration (OSHA) and National Institute of Health (NIH) hazardous conditions may include areas where the oxygen concentrations fall below 19.5% or above 23.5% and require oxygen deficiency monitors.


The Multi Gas Safety System allows you to pick and choose only the components you need to create a fully integrated system. See them below, or contact a CO2Meter expert for more information on your application.
