Description
For scientists and professionals who need precise water content determination from 1 ppm to 5%, the HI904 is a reliable Coulometric Karl Fischer titrator that gives results in minutes. Unlike volumetric Karl Fischer titrators, the HI904 features an precision titrant generation system and a fully sealed titration vessel for unmatched accuracy.
