AMI Oxytrace QED

Maintenance

A-96.250.531 / 300617

6.6.

Zero-Verification

Swansensor Oxytrace G for the measurement of low oxygen con-

tent (< 1 ppb).

Calibrate the sensor according to chapter

Calibration, p. 47

Prepare a 5%-sodium sulfite solution with demineralized water.

Put the electrode into the sodium sulfite solution afterwards. As-

sure that there are no air bubbles in front of the sensor.

The measured value should now be < 1 ppb.

NOTICE:

Depending on the state of the electrode this process

can take several hours. In case of an electrode-refill, this can
take days until the measured value is lower than 1 ppb.
