The HI-904 Karl Fischer Coulometric titrator is an automatic titrator that complements our wide range of products dedicated to efficient and accurate laboratory analysis. The HI-904 analyses for water content ranging from 1ppm to 5%. This powerful titrator effectively monitors the KF reaction, detects the endpoint, and performs all necessary calculations and graphing.

• Precision dosing system by generator electrode – 400mA pulsed current, available with or without a diaphragm
• Molecular sieve desiccant – prevents the ingress of ambient humidity into the sealed solvent system while maintaining full titrator functionality; Regenerated at 300°C
• Sealed Cell – generator electrode; Dual pin bivoltammetric platinum sensing electrode; Molecule sieve desiccant cartridge; Replaceable septum for liquid sampling port; Accessory port
• Built-in stirrer – Automatic, integrated magnetic stirrer adjustable from 200-2000RPM; optical feedback for automatic speed control
