Model 306 Ozone Calibration Source

• The 2B Tech Model 306 Ozone Calibration Source is a portable source of ozone that allows you to calibrate any ozone monitor - not just those manufactured by 2B Tech. The instrument scrubs ozone from ambient air and produces any mixing ratio of ozone in the range 30 to 1,000 ppbv.
• Produces ozone using the UV Photolysis of O2 at 185 nm with an accuracy of 2 ppbv or 2% of ozone concentration.
• It comes calibrated against a NIST-traceable ozone standard, and has the Autocalibration Scheduler function.

Model 714 NO2/NO/O3 Calibration Source

• Economically calibrate 3 pollutant gases using one convenient & portable instrument without the need for a compressed cylinder of nitric oxide.
• Calibrated concentrations of O3 are produced by photolysis of oxygen in scrubbed ambient air, and calibrated concentrations of NO are produced by photolysis of nitrous oxide, N2O, via a patent-pending process. Nitrous oxide is provided by disposable 8 or 16 oz cartridges. Calibrated concentrations of NO2 are produced by gas phase titration (GPT) of NO with O3.
• The concentrations of all three pollutant gases are directly traceable to the NIST photometric standard for ozone – eliminating uncertainties associated with the stability of nitric oxide standards.
• Attractive features include: intuitive Touch-screen user interface, Programmable Calibrated Gas Output - up to 99 different sequences, stored in internal memory.
