Fixed, or Wall-Mounted O2 Monitors by CO2Meter are designed to be wired and used in one central location, providing instant indication should hazardous gas levels be present. Our Wall Mount O2 devices usually include one remote monitor and one central sensor.
Which O2 Monitor is most Accurate?
Regardless of where you purchase your Fixed/Wall-Mount CO2 Monitor, the most accurate O2 monitoring devices and systems use Electrochemical (EC) or UV Flux sensing at their core.
Where shoulda an Oxygen (O2) Monitor be placed?
The breathing zone refers to the area 4 - 6 ft (1.2 - 1.8m) from the floor where most human breathing takes place. This is a good default location for sensors, as many gases often disperse well in air. Sensors should be placed near the source of the gas if possible.
What determines hazardous O2 levels?
OSHA defines indoor air that is less than 19.5% oxygen, as "oxygen-deficient". On the other spectrum, for enrichment OSHA defines this as any atmosphere that contains more than 22%.
Below you will find our most popular O2 wall mount devices that are designed specifically for measuring oxygen depletion or enrichment.
