The 2B Technologies Model 202 Ozone Monitor™ is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~1 ppb) up to 100,000 ppb (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 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

The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.

Options

• Flash Card Memory for virtually unlimited, portable data storage
• GPS for continuous logging of latitude, longitude and altitude
• Rechargeable metal hydride battery provides 12 hr of continuous operation
• External particle filter
• Serial-to-USB adapter
• Rotary vane air pump for low temperature and quiet operation
• External air pump for long pump life
