The results show that uv at 253.7nm of ozone has a large absorption coefficient, and uv at this wavelength is attenuated by ozone, which conforms to Lambert-Beer law. Ozone sensor adopts ultraviolet absorption detection principle.
Ozone gases decay to form oxygen under the action of temperature, humidity, time and air agitation. So measuring ozone in a consistent way is tricky. In this guide, we cover basic information about ozone detectors and tips for ensuring accurate measurements.
