    • pH

    pH is measured by a pH Meter with an electrochemical pH electrode that indicates the acidity or alkalinity of the liquid. It is a critical parameter in water and wastewater treatment in municipal and industrial applications, chemical production, agriculture research and production. pH Meters are also used in environmental monitoring, chemical and life sciences research, biochemical and pharmaceutical research, electronics production and many more applications.

    All pH testers must purchase with calibration solution for tester calibration
