(nasa) So, how does the Ozone gas stays in that altitude without …
WebFigure 5 shows the ozone gradient versus electrode thickness for a single perforated electrode design. Increasing the thickness from 200 to 700 pm results in an increase in the ozone output gradient. This also provides another example of how changing the fraction (%) of DSC in the design leads to improvements in cell EOP performance.

WebAn ozone analyzer measures the real-time ozone concentration in the air. Ambient air is drawn through a sampler inlet from the top of a 10-meter tipping tower by a pump. A filter located at the top of the tipping tower removes particles like dust and pollen from the air sample to prevent them from reacting with ozone before it reaches the analyzer.
