APPENDIX 1: The Model 108-L Ozone Monitor 1. INTRODUCTION - OZONE MONITOR The 2B Technologies Model 108-L Ozone Monitor inside your AQLite is designed to enable accurate measurements of ozone in air over a wide dynamic range extending from a few parts-per-billion by volume (ppb) to parts-per-million (ppm) levels based on the well-established technique of absorption of ultraviolet light at 254 nm. - Page 52 The pressure and temperature within the absorption cell are measured so that the ozone concentration can be expressed as a mixing ratio in parts-per-billion by volume (ppbv). The following animated video developed by 2B Technologies provides a detailed explanation of how this and other UV-based ozone monitors measure ozone.
