Description
HI904 Karl Fischer Coulometric
Karl Fischer Coulometric HI904
The Karl Fischer Titrator HI904 is a type of karl fishers whom measure the amount of water in solutions in coloumetric method and the measuring range is from 1 ppm to 5% that people can achieve the results they need in just a few minutes.
the HANNA HI904 achieve the reults with high accuracy because of precise titrant recovery system and a fully sealed titration tank .
The details of Features included in HI904 been listed as below:
- 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
