Our O2 depletion sensors and monitors are used as a safety solution to monitor confined spaces and alert individuals if O2 levels fall below 20.9%.

  • Protect employees and staff from oxygen depletion hazards or asphyxiation
  • Gain accurate visual and audible alarm should O2 levels reach a dangerous threshold
  • Ensure long-lasting protection with O2 sensing technology that lasts 5+ years

Cryogenic fluids are a special sub-set of pressurized gases. Cryogenics is the science of very low temperatures. In general, all temperatures below 120 Kelvin (-244°F or -153°C) are considered cryogenic.

At these temperatures, nitrogen, oxygen, helium, methane, and argon all become liquids. With the exception of oxygen, all of these gases are asphyxiating. An asphyxiate gas is a nontoxic or minimally toxic gas that reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation or suffocation. Making the need for oxygen depletion monitoring, vital.
