Fast measurements are especially desirable for aircraft and balloon measurements where high spatial resolution is needed. For 10-s averaging, a precision of 1.0 ppb is achieved. Alternatively, one can choose to average more points internally to obtain even better precision. Flash card memory and a long-life, quiet internal air sampling pump are now standard on the instrument.
The Model 205 Dual Beam Ozone Monitor has been approved by the EPA as a Federal Equivalent Method (FEM) based on a modification of the Model 202: EQOA-0410-190.
Features:
- Quiet long-life internal air pump (now standard)
- Low power consumption (~8 watt)
- Internal data logger (EEPROM), logs 16,383 lines of data
- Both serial and user-scalable analog voltage outputs (4-20 mA current output optional)
- Flash card memory (SD card) for virtually unlimited, portable data storage
- 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 2 s or data averaging times of 10 s, 1 min, 5 min and 1 hr (custom averaging times available)
- DewLine™ for elimination of any water vapor interference, a unique feature of 2B Tech instruments
- Dual beam feature allows for heightened precision and improved baseline stability for applications where high spatial resolution is required.
