Description
Hanna Karl Fischer Volumetric Titrator For Moisture Determination HI903
 

Precision titrant delivery system

  • 40,000 step, piston dosing pump
  • Accurate to 0.1%
  • Delivers as little as 0.125 L 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

 

Beaker top

  • Chemically-resistant reaction vessel cap and fittings
  • Quick-remove sample port plug with replaceable silicone rubber septum

 

Anti-diffusion burette tip

  • Delivers titrant in high turbulence zone, ensuring rapid reaction
  • Prevents unwanted diffusion of titrant

 

Built-in stirrer

  • Automatic, integrated magnetic stirrer adjustable from 200-2000 RPM
  • Optical feedback for automatic speed control
  • Optional external stirrer available

 

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 150C

 

PTFE bottle cap

  • Caps fit any GL45-threaded bottle
  • Chemically resistant caps and fittings
  • Removable desiccant cartridges

 

Adaptable, High Accuracy Moisture Determination

The HI 903 Karl Fischer Volumetric Titrator for moisture analysis is an extension of HANNAs 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.

The result is an extremely adaptable titrator capable of titrating with superior accuracy and precision even for samples with low moisture content. The HI 903 dispenses the titrant, detects the endpoint and performs all necessary calculations automatically.

The HI 903 comes equipped with a solvent handling system to reduce cell conditioning time and can be connected directly to your laboratory balance via serial interface.

The HI 903s powerful software and intuitive menus are easily navigated on the large, color LCD display making it simple to view results. Choose from included methods or develop a custom method for almost any application or sample type. Using a USB flash drive or connecting the titrator to the HI 900PC application, methods (standard and user) can be upgraded, stored or deleted.

Clip-Lock Exchangeable Burette System

With Clip-Lock, it only takes a couple of seconds to exchange the reagent burettes to perform a different titration.

The Clip-Lock exchangeable burette system prevents cross contamination while reducing loss of time and reagents. Burettes simply slide out for quick exchanges, and detaching the aspiration and dispensing tubes from the titrant bottles is easy.

Interrupting an important cycle of analysis due to a malfunctioning burette is a thing of the past. With the HANNA Clip-Lock system you can simply substitute the burette and complete all your tests with the same titrant! Having several prepared burettes on hand will make the HANNA HI 903 one of the fastest and most versatile titration systems available.
