Model 202 Ozone Monitor The 2B Technologies Model 202 Ozone Monitor is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~1.5 ppb) up to 250,000 ppb (0-250 ppm) based on the well-established technique of absorption of UV light at 254 nm. The Model 202 Ozone Monitor is lightweight (5.5 lb., 2.5 kg.) and has a low power consumption (12V DC, 0.60 amp, 7.2 watt) relative to conventional instruments and is therefore well suited for applications such as: Vertical profiling using balloons, kites, RPVs and light aircraft where space and weight are highly limited Long-term monitoring at remote locations where power is highly limited Urban arrays of ground-based detectors Personal ex*ure monitoring for studies of health effects of air pollutants Environmental health and safety monitoring Laboratory studies of the effects of ozone ex*ure on materials and organisms Flash card memory and a quiet, long-life internal air pump are now provided standard on the Model 202 Ozone Monitor. The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.
