O2 monitoring with the Safe-Ox+

Using ppO2 sensors, the Safe-Ox+ is an ambient oxygen (O2) monitor designed to protect the lives of those working in an environment where enriched oxygen (O2) and/or inert gasses including argon (Ar), helium (He), nitrogen (N2) and liquid nitrogen (LN2) are present.

Safe-Ox+ Legislation

Standards such as OSHA, EH40, Confined Space Act and IMCA D023/D037 advise on permissible limits for oxygen levels.

Analox are committed to helping you achieve your local and application specific legislation, please call us to discuss your requirements.

Enriched oxygen

When enriched oxygen (O2) leaks, it poses a number of risks including fire, explosion and a condition on the human body called hyperoxia which can cause the central nervous system to shut down.

When an inert gas leaks it displaces the oxygen (O2) also posing a risk to life. Even a very small reduction in oxygen (O2) can cause effects on the human body such as headaches, confusion and shortness of breath.

Normal atmosphere contains 20.9% oxygen (O2) and levels should be maintained in any area around this level.

Using an oxygen (O2) monitor, like the Safe-Ox+, is the best way to protect people and your site in these potentially hazardous environments. The Safe-Ox+ also ensures adherence to exposure limit legislation such as OSHA and EH40.

The Safe-Ox+ boasts a very long life sensor and requires very little servicing and maintenance.
