ORP MEASUREMENTS
An optional ORP electrode must be used to perform ORP measurements
(see Accessories).
Oxidation-Reduction Potential (REDOX) measurements provide the
quantification of the oxidizing or reducing power of the tested sample.
The surface of the ORP electrode must be clean and smooth in order to
obtain an accurate measurement.
Pretreatment solutions are available to condition the electrode and speed
up the response time.
• The instrument automatically defaults to the
mV measurement mode if HANNA P type ORP
electrode is detected.
• Submerse the ORP electrode tip (3 cm/1¼”)
into the sample. Allow a few minutes for the
reading to stabilize.
• The instrument displays the mV reading on the primary LCD.
• If the reading is out of range, the closest full-scale value will be
displayed blinking on the primary LCD.

Connect the
HI 7662
temperature probe and turn the
instrument on. Dip the temperature probe into the sample
and allow the reading on the secondary LCD to stabilize.
