Calibration

ProMinent ®
IMPORTANT
The sensor must not be operated in water or solutions
containing surfactants.
IMPORTANT
 A slope test must be carried out after replacing the
membrane cap or electrolyte.
 Slope tests must be repeated at regular intervals to
ensure that the sensor is working correctly! When used
in the treatment of swimming pool or drinking water it is
generally sufficient to re-calibrate the sensor every
3 - 4 weeks.
 Avoid incorrect dosing due to air bubbles in the sample
water! Air bubbles clinging to the sensor membrane can
result in a measured variable that is too low and thus lead
to incorrect dosage.
 Observe applicable national directives for calibration
intervals!
