Measured Variables and Operating Menus for Potentiometric Sensors

7 Measured Variables and Operating Menus for Potentiometric
Sensors
Measured variables: pH, redox, fluoride
CAUTION!
Influence of temperature on the pH or fluo‐
ride measurement
Possible consequence: Slight or minor inju‐
ries, material damage
Temperature changes in the sample water
lead to a change in the gradient of the cali‐
bration lines (pH, fluoride) and to a displace‐
ment of the zero point with pH sensors or
the standard potential E
sensors.
Measure to be taken to avoid this danger:
–
The pH or fluoride measurement
should only be carried out in the
[Temperature Correction Value auto‐
matic] setting
–
The DULCOMETER
automatically compensates for both
effects when a temperature sensor
(Pt 100/Pt 1000) is connected
