Oxygen Gas Transmitter
Application
Household application, offices, indoor parking, Library, hospital, shopping mall and etc.
Features
The oxygen level is a very important indication of indoor air quality. It exists generally, in gaseous state at
room temperature. When people stay in some places with low oxygen level, such as office, commercial
building or basement, it might cause hypoxemia. Chronic fatigue is a major sign that people isn’t getting
enough oxygen. Without enough oxygen in the lungs, the organs cannot function properly. As a result, toxins
accumulate in the bloodstream. NOGT Oxygen gas transmitter can monitor oxygen level and send the data to
monitoring center for analysis or for ventilation control. Air quality can be, therefore, efficiently monitored and
managed.
