Model Dual Beam Ozone Monitor | 2.B Tech

With its double beam, measurements of UV light intensity Io (ozone-scrubbed air) and I (unscrubbed air) are carried out simultaneously. Combined with other improvements, this made it possible to reduce the time between ozone measurements to 2 seconds, making our instrument the fastest UV-based ozone monitor on the market, while still retaining the small size, weight, and power requirements of our popular Model 202 Ozone Monitor. 

Features :

• Quiet long-life internal air pump (now standard)
• Low power consumption (~8 watt)
• Internal data logger (EEPROM), logs 16,383 lines of data
• Real-time clock
• 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.

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

Because of its small size, it can be transported anywhere, and can be calculated very quickly, for example on a light rail platform in Utah, yielding enlightening (and perhaps counter-intuitive) results on ozone levels near busy highways. You can download the application note.
