Online Coulombic Trace Water Analyzer System

Product Introduction

The online Coulomb trace water analyzer system consists of a fully automatic sampling unit, a fully automatic potentiometric analyzer (Coulomb method), a data processing unit, and other systems. The online coulombic trace water analyzer adopts the Karl Fischer Coulomb method for analysis, which fully automatically completes sampling, analysis, cleaning, data calculation, storage and other tasks, suitable for the determination of moisture content of various substances. The whole machine shell adopts a positive pressure ventilation explosion-proof design, which is suitable for use in various complex environments.
