3.2. OXIDATION REDUCTION POTENTIAL MEASUREMENT (ORP)
ORP = Oxidation Reduction Potential
3.2.1. FIRST USE
During the first use, connect the ORP electrode (optional) to the measuring instrument. Connect the connector of the electrode to
the instrument and screw the ring tight.
3.2.2. CALIBRATION
Calibration is done at a single point.
Remove the storage bottle from the electrode.
Rinse the electrode in de-ionized water, then dry it.
