4.6 pH value
4.6.1 General information
You can measure the following parameters:
pH value [ ]
Sensor voltage [mV]
Note
The sensor connection and the USB-B (device) interface are galvani-
cally isolated. This enables interference-free measurements in
grounded measuring media.
Temperature
measurement
For reproducible pH measurements, it is essential to measure the tem-
perature of the test sample. IDS sensors measure the temperature with
a temperature sensor integrated in the IDS sensor.
Preparatory activities Perform the following preparatory activities when you want to measure:
4.6.2 Measuring the pH value
When operating a sensor without integrated temperature sensor, e.g.
via an IDS pH adapter, you have to determine and input the tempera-
ture of the measuring medium first.
1 Connect the IDS pH sensor to the meter.
The pH measuring window is displayed.
2 If necessary, select the measured parameter with <M>.
3 If necessary, calibrate or check the IDS pH sensor.
1 Perform the preparatory activities according to section 4.6.1.
2 Immerse the IDS pH sensor in the test sample.
