The Hi904 Karl Fischer Coulometric Titrator is an automatic titration system for the measurement of trace amounts of water in various samples. The Coulometric Titrator complements our wide range of titration products dedicated to efficient and accurate laboratory analysis. The HI904 analyzes for water content ranging from 1 ppm to 5%. This powerful titrator effectively monitors the Karl Fischer reaction, detects the endpoint, and performs all necessary calculations and graphing.
