2B Technologies O3 Monitor
2B Technologies Ozone Monitor

The 2B Technologies Ozone (O3) Monitor is an in-situ dual-beam ozone monitor suitable for airborne and ground-based use. It measures O3 concentration through dual-beam ultraviolet (UV) absorption at 254 nm. The device has a detection range of 0 to 20 ppm, a resolution of 0.1 ppb, and provides measurements every 2 seconds. Its operating temperature range is 0 to 50 degrees Celsius, with an altitude range of approximately 0 to 13.5 km.
