Industrial Ozone Monitors - 2B TecHnologies

The Model UV-106-W Aqueous Ozone Monitor™ uses our patented MicroSparge™ technology to measure dissolved ozone in water with high precision and accuracy. Unlike most dissolved ozone sensors, the instrument does not make use of a membrane that will foul over time. Instead, dissolved ozone is measured by nearly complete sparging (bubbling) of ~2 mL of water with ozone-scrubbed ambient air and integrating the gas-phase concentration of ozone …

Gas Sensors Ozone -

Ozone is a triatomic form of oxygen, meaning that the molecule, ozone, is made up of 3 oxygen atoms. Unlike oxygen, ozone is a visible gas with a light blue color at very high concentrations. At low concentrations ozone is colorless. Ozone also has a distinct odor that is noticeable at very low levels and may be associated with a “clean” smell, at higher levels ozone has a very pungent odor. Ozone is an unstable gas that readily decomposes to oxygen naturally. Ozone …

Determination of atmospheric ozone concentration through ...

The LEDs and light sensors were specifically positioned such that the 255nm wavelength light would go straight through the sphere to the light sensor while the other wavelengths would bounce around inside the sphere before hitting the light sensor. This is because ozone is very absorbent at 255nm wavelengths, so the 255nm light does not need to travel through as much ozone for there to be a ...
