Model 2022B Ozone Analyzer from the United StatesThe 2B ozone technology in China is designed based on mature 254nm ultraviolet absorption technology to measure ozone levels ranging from low ppb (with an accuracy of~1.5ppb) to 250000 ppb (0-250ppm). Flash memory card storage and a quiet, long-lasting internal air pump are now standard on the 202 ozone monitor. The 202 type ozone monitor is lightweight (5.5 pounds, 2.5 kilograms) and has lower power consumption compared to traditional instruments (12V DC, 0.60 amperes, 7.2 watts), making it very suitable for applications such as:

Conduct vertical profile analysis using balloons, kites, RPVs, and light aircraft, where space and weight are very limited

·Long term monitoring in highly restricted remote areas

Urban Ground Detector Array

Personal exposure monitoring of air pollutants and their impact on health

Environmental Health and Monitoring

Laboratory study on the effects of ozone exposure on materials and organisms
