A room oxygen monitor with a range of 0–23%, the Oxygen (O2) Deficiency Safety Alarm guards against oxygen depletion in personnel. The intended placement for this device is close to sources of inert gases, such as helium, argon, or nitrogen. It can also be utilized in walk-in freezers or refrigerators with a minimum temperature of -50 °C.
Hospitals, labs, pharmaceuticals, cryogenics, process cooling, freezers, manufacturing, and research facilities all use the Oxygen Deficiency Safety Alarm.
