Oxygen (O2) Detector (both for enrichment and depletion)

Oxygen forms some 21% of our atmosphere. At Medem, we primarily deal with oxygen depletion with a pre-alarm at 19% and high-alarm at 18%.

Although we have produced detectors for oxygen enrichment alarm levels would have to be decided on after discussion of the application.

Oxygen Depletion

Oxygen depletion is used as a method of monitoring for inert/noble gases which will cause a displacement of oxygen in the atmosphere acting and asphyxiants.

These gases are often found in laboratories with an example being Nitrogen and Argon.

O2 detectors must never be used to indicate displacement by Carbon Dioxide (CO2) by measuring O2 deficiency.

O2 detectors should never be used to detect toxic gases again by measuring O2 deficiency.

Oxygen Enrichment (O2)

An increase in oxygen levels will accelerate a fire so identifying an oxygen leak is important.
