Over the 5 years I have taken care of my pool I have bought a couple of new salinity meters. Some of the stopped working but many of them started to show to low value after a time.
An example, it shows 3.2 but the real value is 4.0
Have something happened to the sensors. Can I fix it?
Do I have to do a special cleaning after each measurment?
