NEW: WATER FILTER JUG AARKE WITH BWT FILTER TECHNOLOGY
The pH sensor (blue) measures the pH value and helps to estimate the balance of your pool water. Thanks to the "Twist & Lock system", the sensor can be easily replaced.

Your Pearl Water Manager has been calibrated at the factory as standard. After the first season, we recommend that you recalibrate the sensors every time you put your pool or whirlpool back into operation (or every 6 months if you do not winterise) or if you notice a deviation in the measurements.
Contents: 1x pH sensor, 1x pH calibration kit
