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�?00 (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
