the 2b technologies model 202 ozone monitor™ is designed to enableaccurate and precise measurements of ozone ranging from low(precision of ~1 ) up to 100,000 (0-100 ppm) based on the wellestablished technique of absorption of uv light at 254 nm. themodel 202 ozone monitor™ is light weight (4.7 lb., 2.1 kg.) and hasa low power consumption (12v dc, 0.33 amp, 4.0 watt) relative toconventional instruments and is therefore well suited forapplicatio uch as:vertical profiling using balloons, kites, rpvsand light aircraft where space and weight are highlylimitedlong-term monitoring at remote locations where power ishighly limitedurban arrays of ground-based detectorspersonalexposure monitoring for studies of health effects of airpollutantsenvironmental health and safety monitoringlaboratorystudies of the effects of ozone exposure on materials andorganisms
