Online Conductivity Meter to Monitor Pure Water Production
Online Conductivity Meter Installed to Monitor Pure Water Production Conductivity is the ability of a solution to transfer (conduct) electrical current. The value of the electrical conductivity is dependent on the ability of electrons or other charge carriers to move within a liquid. The inverse of this is resistivity. Resistivity describes the ability of a…
