Product Introduction

 Product Description

The product is based on electrochemical principles of the coulometric titration, use the potassium dichromate (K2CrO7) as the oxidant, reflux digestion of reducing substances in sulfuric acid medium, and use silver sulfuric acid as catalyst,过量的重铬酸钾produced by electrolysis Fe2+ as a reductant titration(Also known as electric titration),electric counterpoint determine titration end point,according to consumption of electricity, use the computer-chip microcomputer  to calculate the COD value of the sample.
