Product Introduction

The ESN1000 ORP Analyzer is an important tool for measuring the oxidation-reduction potential in solutions. The ORP analyzer determines the ORP value by measuring the ability of electron transfer between oxidants and reductants in the solution, providing important data support for related industries.
