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: ‚Äč

  • 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

System Includes

  • Model 202 Ozone Monitor with quiet, long-life internal air pump
  • AC Power Adapter (100-240 VAC to 12 VDC) with Country-Specific Plug
  • Flash Card Memory for virtually unlimited data storage
  • SD Card
  • SD Card Reader
  • Cigarette Lighter Adapter
  • Zeroing Cartridge
  • Operation Manual on USB Stick
  • Calibration Data and NIST-Traceable Calibration Certificate
  • Instrument Birth Certificate
  • One-Year Warranty

Options

  • GPS for continuous logging of latitude, longitude, and altitude (for 10-s data mode and above)
  • Rechargeable lithium-ion battery provides 12 hours of continuous operation
  • External particle filter
  • Serial-to-USB adapter
  • 4-20 mA analog current output
  • Bluetooth for wireless data transmission
  • Low-temperature package for operation to -20 degrees C (pump, lamp heater)
  • High-altitude upgrade (pressure sensor for use up to 25 km altitude)
  • Extra long-life, low temperature internal air pump
  • Low-power option for even lower power consumption
  • Rack-mount case configuration
