mV, ORP measurement
You can measure the electromotive force between the electrode and the sample by
using a pH electrode. The mV value can be used to understand the status of the
electrode in the mV measurement.
You can measure the ORP (oxidation-reduction potential) of the sample by using an
ORP electrode in the ORP measurement.
In the measurement mode, press the
"mV".
mV and ORP can be measured using channel 1 of the instrument.
● Switching between absolute value and relative value
There are two types of measurement mode for the mV and ORP measurement, the
absolute value measurement and the relative value measurement.
• Absolute value measurement mode
The measured value of electromotive force is displayed.
• Relative value measurement mode
The measured value of electromotive force of a sample is corrected to 0 mV and set as
a relative value. When the electromotive force of another sample is measured, the
difference value between the relative value and the measured value is displayed.
The default mode is the absolute value measurement mode. Pressing the
switches to the relative value measurement mode. Pressing the
the absolute value measurement mode.
