Maintenance
!
Note!
• Service the sensor regularly to avoid incorrect dosing within a control system, due to incorrect
measured value.
• Do not touch the electrodes or allow them to come into contact with greasy substances.
• Never attempt to clean the membrane with acid/alkaline solutions, cleaning reagents or
mechanical aids (brushes or similar).
Maintenance intervals based on experience are:
• Drinking, industrial, process and cooling water: depending on the specific conditions
(1-4 weeks)
• Swimming pools: weekly
• Whirlpools: daily
Perform the following maintenance work:
• Check the sensor for dirt, algae and air bubbles. If neccessary clean the sensor with clear water
and a soft tissue. Eliminate air bubbles by increasing the flow rate.
• Check the displayed sensor value on the transmitter according to the DPD 1 / DPD 3 method.
Use a photometer (e.g. CCM182 , see accessories).
• If necessary, recalibrate the sensor.
• If calibration cannot be carried out properly, replace the membrane cap and repeat the
calibration.
