ProMinent DULCOMETER D1Cc - Temperature Correction Value for Ph and Fluoride Sensors

8.6 Temperature correction value for pH and fluoride sensors
CAUTION!
Influence of temperature on the pH or fluoride measurement
Possible consequence: Slight or minor injuries. Material damage.
Temperature changes in the sample water lead to a change in the slope of the cali‐
bration lines (pH, fluoride) and to a displacement of the zero point with pH sensors or
the standard potential E
S
for fluoride sensors.
Measure to be taken to avoid this danger:
–
The pH or fluoride measurement should only be carried out in the
[Temperature Correction Value automatic] setting
– The DULCOMETER
®
D1Cb / D1Cc then automatically compensates for both
effects when connecting a temperature sensor (Pt 100/Pt 1000)
