KI-90200 Automatic Karl-Fischer Volumetric Titrator

The instrument utilizes a microprocessor controller for rapid and easy determination of water content in petroleum and petrochemical products as well as for solid and liquid samples. The dual pin platinum electrode provides a measuring range of 10 µg to 500 mg of water. The end point is voltametrically detected automatically with the proper accuracy and precision as prescribed by ASTM specifications.

Description

The actual curve and the measurement drift during titration process appear in the display and you can see the titration solvent consumption. Standard methods for different applications are programmed.

The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms. The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in ppm water or several other units.
