The conductivity sensor (grey) measures the TDS value (number of dissolved solids in the water) and helps to estimate the chlorine-bromine content or salt content of your pool or spa 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 start up your pool or hot tub again (or every 6 months if you do not winterise) or if you notice a deviation in the measurements.
