Product Overview

2b Technology Gas MonitoringYe

The 2B Technologies 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.  The desired ozone concentration is chosen from the easy-to-use menu using a rotary select switch, or can be controlled remotely via the serial menu.  The total output flow rate is 3.0 L/min volumetric, and the ozone mixing ratio is controlled so as to be independent of ambient temperature, pressure, and humidity.  You can attach the Ozone Calibration Source (OCS™) output directly to the inlet of any ozone monitor; the excess flow is vented through an ozone scrubber internal to the OCS.  Although the instrument comes calibrated against a NIST-traceable ozone standard, the menu allows the user to change the calibration parameters of the ozone output if desired.  For example, if you maintain an ozone reference instrument in the lab, you can use the OCS as a transfer standard for calibrating ozone instruments in the field relative to your lab standard.  The scheduler function allows you to schedule an autocalibration once daily that executes a series of up to 10 programmable output steps.


  • Calibration of ozone monitors in the field.  This highly portable transfer standard is especially useful for maintaining the calibrations of networks of ozone monitors.
  • Testing of materials such as rubber, plastics and paint for effects of ozone exposure.
  • Studies of the effect of ozone on plants where a calibrated source of ozone is required
