Low cost, battery powered Oxygen Deficiency Monitor  providing continuous monitoring of concentrations in the surrounding air and both visual and audible alarms when these fall outside pre-set levels.

The One O2 includes a long life three year oxygen sensor.  Continuous monitoring is achieved with a battery powered system which eliminates the need for wiring to mains.

The One O2 may be used as a standalone device with its own audible and visual alarms or linked to other repeater modules to mimic the condition of the monitor.  Further modules can be easily added at a later stage to expand the scope of the system.


The One O2 monitor is ideal for single room set ups providing reliable operation with minimal installation by simply screwing to the wall. The concentration of oxygen in the surrounding air is continuously monitored and provides two alarm states: Alarm and Critical Alarm. In the event that oxygen levels fall outside of these alarm states, the system provides visual and audible alarms to ensure the safety of personnel.
