Conductivity
Conductivity is a measure of water's ability to conduct electricity, which increases with the concentration of dissolved ions.
Definition
Conductivity is a measure of water's ability to conduct electricity, which increases with the concentration of dissolved ions.
Typical Values: Salt pool target: approximately 5,000–6,000 µS/cm (corresponds to ~3,000–3,400 ppm salt)
In Plain Language
Higher TDS in pool water increases electrical conductivity. In salt pools, conductivity is a secondary measure of salt concentration. Some digital water testing devices measure conductivity as a proxy for TDS or salt level. Conductivity is measured in microsiemens per centimeter (µS/cm) or millisiemens per centimeter (mS/cm). Salt pool salt meters often actually measure conductivity and convert the reading to estimated salt concentration.
Why It Matters
Conductivity-based salt meters are common in salt pools. Understanding how they work helps interpret their readings correctly.
