ZSD-2JModel Intelligent Automatic Moisture Measuring InstrumentNanjing Kehuan Analytical Instruments Co., Ltd.The newly developed next-generation moisture titrator, isKF-4Advanced model automatic moisture meter, featuring new mechanical and electronic design technology and user-friendly interface design philosophy. Measurement accuracy significantly improved, operation and usage simplified and convenient. The instrument uses the Karl Fischer volumetric method to determine moisture, capable of measuring crystalline water, adsorbed water, and free water in liquid, solid, and gas samples. Widely applicable in industries such as petrochemicals, daily chemicals, food, agriculture, and laboratories.

1.1  Key Features

        1.1.1  The reaction endpoint is determined by the polarization voltage of the dual platinum electrodes, and the titration is terminated accordingly.

        1.1.2  The system is fully enclosed, capable of automatically replacing solvents and draining waste liquids, preventing the escape of toxic reagents.

        1.1.3  Measurement results are automatically memorized.

        1.1.4  Blending PWM variable speed, select from the operation menu.

        1.1.5  Extra-large color TFT touch LCD screen, with touch LCD menu operation.

        1.1.6  Real-time dynamic prompts, Windows-style interface, easy to use.

        1.1.7  Multiple results (moisture content, percentage content, ppm content, Kjeldahl nitrogen) displayed simultaneously. Colorimetric titration curves dynamically displayed.

        1.1.8  Instrument status, sample volume of metering pump, current time, three-way valve position, and electrode measurement values are displayed in real-time.

     1.2  Cautionary Notes

 1.2.1  If the instrument is not to be used for an extended period, all Kjeldahl reagents and waste liquids in the fluid path should be drained, and then the path should be cleaned repeatedly with anhydrous methanol.     And reaction beakers (specific operations see Maintenance and Care section).

 1.2.2  Please carefully read this user manual before use.Set parameters correctly.
