pH, ORP, CONDUCTIVITY VIDEO
This video from Control's Back-to-Basics series explores wet chemistry measurements; shows how density, pH, ORP and conductivity are deceptively simple and similar; and covers density analyzers, too. Control former editor Walt Boyes demonstrates how to understand and differentiate between these three measurements.
