7.6 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 gradient of the calibration lines
(pH, fluoride) and to a displacement of the zero point with pH sensors or the standard potential E
with fluoride sensors.
S
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
temperature sensor (Pt 100/Pt 1000) is connected
