Microsense sf6 o2 Components Detection for proper equipment

Accurate oxygen (O2) level measurements are essential in preventing injury in situations where safe levels may be compromised. A most common form of detection is Oxygen depletion. An oxygen gas detector provides a first-level alarm when the oxygen concentration dropped 19.5%. Most people will begin to behave abnormally when the level reaches 17.5%.
