Product Description 
The Hanna HI 904 Karl Fischer Coulometric Titrator for moisture analysis measures 1 ppm to 5% water content.

The HI904 combines an ultra-high electrolytically generated iodine dynamic dosing system with optically-regulated magnetic

stirring, sophisticated endpoint determination, and background drift correction algorithms. The result is an extremely adaptable titrator capable of titrating with superior accuracy and precision for samples with low moisture content. The HI904 applies a pulsed DC current for titrant generation, detects the endpoint and performs all necessary calculations automatically.

The HI904 comes equipped with a solvent handling system to reduce cell conditioning time and can be connected directly to a laboratory analytical balance via RS232 serial interface. The HI904's 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. Methods (standard or user) and reports can be transferred between titrator and PC via USB interface by using the Hanna


PC software. Software updates can be performed using a USB flash drive.
​
Frit-less (no diaphragm) generator electrode - uses one easy-to-replace Karl Fischer reagent because the anode and cathode reactions take place in the same electrolyte

lower and more stable drift rates
easier cleaning of generator cell
no contamination of a diaphragm
good for hydrocarbons, alcohols, esters, ketones and oils

Precision dosing system by generator electrode
