The HI 903 Karl Fischer Volumetric Titrator for moisture analysis is an extension of HANNA’s highly successful potentiometric titrator platform. The HI 903 combines an ultra-high precision titrant delivery system with optically regulated magnetic stirring, sophisticated endpoint determination, dynamic dosing and background drift correction algorithms.
Precision titrant delivery system
- 40,000 step, piston dosing pump
- Accurate to 0.1%
- Delivers as little as 0.125 µL of titrant
- Precision ground, 5 mL glass burette with PTFE plunger, PTFE burette tubing, and polyurethane tube jacketing (thermally insulating, light blocking)
- Glass anti-diffusion dispensing tip
- Clip-Lock™ exchangeable burette system enables users to exchange reagent burettes in a matter of seconds
Sealed solvent system
- Change to fresh solvent in a matter of seconds without opening the titration vessel
- Minimizes exposure to ambient humidity, reducing titrant consumption and saving time
- PTFE solvent tubing is resistant to harsh KF solvents and titrants
Rechargeable indicating desiccant
- Prevents the ingress of ambient humidity into the sealed solvent system while maintaining full titrator functionality
- Minimizes changes to titrant titre
- Indicates when adsorption capacity is depleted
- Regenerates at 150°C
