Product Overview
Model 202 Ozone Monitor
EPA Federal Equivalent Method (FEM)
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. Flash card memory and a quiet, long-life internal air pump are now provided standard on the Model 202 Ozone Monitor. 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 exposure monitoring for studies of health effects of air pollutants
- Environmental health and safety monitoring
- Laboratory studies of the effects of ozone exposure on materials and organisms
