HI 903 Karl Fischer Volumetric Titrator from Hanna Instruments

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
