Description
Karl Fischer Titration – Coulometric Titrator for moisture determination
The HI-904 Karl Fischer Titration instrument is an automatic titrator that complements our wide range of products dedicated to efficient and accurate laboratory analysis. Measures 1ppm to 5% water content.
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.
Features include:
- 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
- Sealed solvent system – Change to fresh reagent in a matter of seconds without opening titration vessel; minimises exposure to ambient humidity; PTFE tubing is resistant to harsh KF Chemicals; sealed tube holder to collect PTFE tube after exchanging reagent
- PTFE bottle cap – Caps fit any GL45-threaded bottle; chemical-resistant caps and fittings; removable desiccant cartridges
