The 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 (12 VDC, 0.6 A, 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 effectes of ozone exposure on materials and organisms
Features:
- Quiet, long-life internal air sampling pump
- DewLine™ for elimination of any water vapor interference, a unique feature of 2B Tech instruments
- Interal data logger (EEPROM), logs 16383 lines of data
- Low power consumption: ~7.2 watts
- Flash card memory (SD card) for virtually unlimited, portable data storage
- Both serial and user-scalable analog voltage outputs (4-20mA current output optional)
- Three 0-2.5 VDC analog inputs for logging other measurements, such as external temperature, pressure, and humidity
- Convenient user interface to microprocessor, including calibration parameters (gain and zero)
- Selectable measurement time of 10s or data averaging times of 1min, 5min and 1hr (custom averaging times available)
- Selectable units for ozone, pressure and temperature
The Model 202 has been designated by the EPA as Federal Equivalent Method (FEM): EQOA-0410-190.
