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
