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. The scheduler function allows you to schedule an autocalibration once daily that executes a series of up to 10 programmable output steps.
The Ozone Cal Source™ is housed in the same small, rugged instrument case as the Model 202 and Model 205 Ozone Monitors™.
Some applications of the Model 306 Ozone Calibration Source™ include:
- 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.
