Product Introduction

The ESN1000 Conductivity Analyzer determines the conductivity of a solution by measuring its ability to conduct electricity. The conductivity of a solution is closely related to its ion concentration and temperature. The instrument typically applies an alternating voltage across two electrodes and measures the current to calculate conductivity. Proper selection and use ensure accurate measurement results.
