Measuring The Redox Voltage - wtw inoLab pH/Cond Level 1 Operating Manual

Note
The current AutoRead measurement (with acceptance of
the current value) can be terminated at any time by pressing
g
. It is only possible to change to another measuring mode
after AutoRead has been terminated.

4.2.2 Measuring the Redox voltage

The instrument can measure the Redox voltage (mV) of a
solution when connected with a Redox electrode, e.g.
SenTix ORP.
1 Perform the preparatory activities according to sec-
tion 4.2.
2 Immerse the Redox electrode into the test sample.

3 Press the
status line.
The Redox voltage (mV) of the sample appears on
the display.
4 Wait for a stable measured value.
Note
The AutoRange function is always active and automatically
switches to the measuring range with the highest resolution.
Note
Redox electrodes are not calibrated. However, you can
check Redox electrodes using a test solution.
