The oxygen gas detector, oxygen depletion monitor
Indispensable for humans and their environment, oxygen is essential for life and unlike the vast majority of gases, the lower the oxygen (O2) concentration, the more dangerous the effects on health. It is therefore essential to control the oxygen content - with an oxygen detector - when a potential risk of anoxia may arise.
In ordinary ambient air, its concentration is 20.9% / vol, when this rate drops below 19% / vol., The air is considered to be depleted in oxygen and less than 16% / vol. the air becomes dangerous for humans.
The oxygen gas detector: anoxia risk prevention
Anoxia represents an important risk for workers' safety and health. Many classic work situations that can appear harmless can actually produce favorable conditions for oxygen depletion. For example using inert gases (nitrogen, helium, argon or carbon dioxide) in universities, laboratories, research centers. Working is confined spaces ( crawlspaces, sewers, tanks, underground, etc...) can also be dangerous. The use of an oxygen gas detector as an PPE (personal protective unit) is essential, even mandatory on particular work sites.
The O2 detector: an essential PPE
Oxygen gas detectors (rather "lack of oxygen detectors") can be broken down into several versions: from the single gas monitor (disposable or not) up to the multi gas detector that can combine an O2 sensor with other gas sensors (combustible gas, CO, H2S, CO2, etc).
The most affordable device remains the disposable O2 detector that will be continuously monitoring for 2 years without any needed maintenance or sensor or battery replacement. Which makes it a very useful and beneficial device.
