The 2B Technologies Model 202 Ozone Monitor™ is designed to enable accurate and precise measurements of ozone ranging from low （precision of ~1 ） up to 100,000 （0-100 ppm） based on the well established technique of absorption of UV light at 254 nm. The Model 202 Ozone Monitor™ is light weight （4.7 lb., 2.1 kg.） and has a low power consumption （12V DC, 0.33 amp, 4.0 Watt） relative to conventional instruments and is therefore well suited for applicatio uch as:Vertical profiling using balloons, kites, RPVs and light aircraft where space and weight are highly limitedLong-term monitoring at remote locations where power is highly limitedUrban arrays of ground-based detectorsPersonal exposure monitoring for studies of health effects of air pollutantsEnvironmental health and safety monitoringLaboratory studies of the effects of ozone exposure on materials and organisms
The Model 202 has been designated by the EPA as a Federal Equivalent MethodOptionsFlash Card Memory for virtually unlimited, portable data storageGPS for continuous logging of latitude, longitude and altitudeRechargeable metal hydride battery provides 12 hr of continuous operationExternal particle filterSerial-to-USB adapterRotary vane air pump for low temperature and quiet operationExternal air pump for long pump life
