Description
Overview
GAOTek Portable Conductivity Tester is a versatile instrument equipped with six distinct measurement modes. This device is adept at measuring various key parameters including pH, ORP (Oxidation-Reduction Potential), conductivity, TDS (Total Dissolved Solids), salinity, and resistivity. Its multifunctionality makes it a valuable tool for a wide range of applications where precise and comprehensive water quality analysis is required.
