HI903-01 Volumetric Karl Fischer Titrator
Unlike other Karl Fischer titrators, the HI903 features an ultra-high precision dosing system and a specialized burette design for unmatched accuracy.
A Better Volumetric Karl Fischer Titrator Experience Our friendly technical consultants take pride in helping make your titrator selection easy – every step of the way. Our experts are here to guarantee you have a positive experience, from onsite installation and training to customization and continued support.
The HI 903 Karl Fischer Volumetric Titrator for moisture analysis combines an ultra-high precision titrant delivery system with optically regulated magnetic stirring, sophisticated endpoint determination, dynamic dosing and background drift correction algorithms. The HI 903 dispenses the titrant, detects the endpoint and performs all necessary calculations
automatically. It comes equipped with a solvent handling system to reduce cell conditioning time and can be connected directly to your laboratory balance via serial interface.
- Data can be transferred to a PC using the HANNA HI 900PC software application
- The USB port allows for the easy transfer of methods, reports and software upgrades via a USB flash drive
- Users can print reports of analyses directly from the titrator using a standard parallel printer
- An external monitor and keyboard can be attached for added versatility
Beaker top
- Chemically-resistant reaction vessel cap and fittings
- Quick-remove sample port plug with replaceable silicone rubber septum
Anti-diffusion burette tip

Proper mixing of titrant and analyte
- Digital, magnetic stirring system with optical feedback
- Conical titration cell to facilitate mixing over a wide volume range
- Upward dispensing of titrant to ensure rapid reaction
Flexible, accurate detection of the titration endpoint
- Dual platinum pin polarization electrode for bivoltametric indication
- Signal averaging reduces noise
- Selectable endpoint criteria: fixed mV persistence, relative drift stop or absolute drift stop
Balance interface
- Automatically acquire sample mass or volume via serial RS-232 interface
Easy to operate
- User friendly interface
- Context-sensitive help screens
- Self diagnostic features for external components including dosing pump, burette and stirrer
Ideal for food and beverage, pharmaceuticals, cosmetics, chemical and petrochemical manufacturing and solvents
