- 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
