To perform the recalibration the following instruments are needed:
- Known concentration gas cylinder suitable for the sensor, equipped with a pressure regulator
- Flow meter
- Hose with T-fitting to connect the cylinder to the flowmeter and to the instrument
WARNING!
For the oxygen sensor on site calibration, the zero value calibration must be carried out with nitrogen or
any other gas mixture which DOES NOT contain oxygen.

WARNING
Be sure that the autozero is performed in clean fresh air and that it terminates
