Coulometric Karl Fischer Titration method is used to carry out moisture estimation in many specific applications. The Coulometric titration process involves constant current electrolysis using electrolytic control method. An intermittent electrolysis is employed to get the exact end point.

Spectralab Model CM - 08 is based on the principle of Coulometry. It detects the moisture content from 1ppm to 5%. In this method the reagent is generated electrolytically in the titration vessel. the moisture is calculated by using the titration time and the constant current passed. It is micro controller based, reliable & easy to use.
