Ozone is an unstable gas that decays to form oxygen and is therefore tricky to measure in a consistent fashion. Ozone gas also has oxidization properties, making it a useful disinfectant for cleaning and abatement companies. Ozone is also toxic to human health and must be measured for inhalation protection. Ozone gas detectors are used for personal protection within OSHA levels, sanitization and disinfection protection, water treatment, ozone control systems, and in research and development.
