PSI Ozone
PSI Ozone Dual-Beam UV-Absorption Photometer

The PSI Ozone Dual-Beam UV-Absorption Photometer is an in situ airborne photometer manufactured by Physical Sciences, Inc. (PSI). It uses dual-beam absorption at 254 nm to measure ozone concentrations. It operates similarly to the NOAA Ozone photometer but with improved thermal stability, lower power consumption, and a lower flow rate. PSI Ozone has a typical data rate of 1 Hz and a detection sensitivity of 1 ppb at sea level.
