      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 MethodOptions

    • 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

    System Includes

    • Model 202 Ozone Monitor
    • AC Power Adapter (100-240 VAC to 12 VDC) with Country-Specific Plug
    • Cigarette Lighter Adapter 
    • Battery Wire Connector
    • Zeroing Cartridge
    • Operation Manual on CD
