Coulometric Karl Fischer Titrator FM-AKT-A100 is a two chamber electrolysis method of titration for determination of water content in petroleum products, lubricating oils and additives by Karl Fischer reagent. Samples with water content between 1 ppm and 100% are analyzed in single measurement using alternate current polarization method of endpoint detection. Twin platinum electrode and maximum electrolysis speed of 40 μg H2O/s enables fast and precise moisture determination with very simple operation.
