What does a conductivity meter measure in water?
Conductivity is a physical quantity that describes the electrical conductivity of a liquid or substance. It represents the voltage required to pass a current per unit length through a unit cross-sectional area. Conductivity is the reciprocal of conductance, and the unit is S/m. Conductivity is an important parameter used to measure the conductivity of a substance, which depends on the concentration and mobility of free charge carriers in the substance. In a more conductive substance, the...
