Electrochemical System (ECS)

Introduction

The Electrochemical System is an Analytical Instrument used to determine the various electro-active species present in the sample solution under test. It works on the principle of measurement of Current or Voltage in an Electrochemical Cell under the application of Voltage or Current in predefined manner respectively.
