    Equipments Details


    The automatic HI904 Karl Fischer Coulometric Titrator is used for the determination of moisture in samples that range from 1 ppm to 5% water content. It 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. Specification: Range: 1 ppm to 5% Resolution: 0.1 ppm to 0.0001% Result units: %, ppm, ppt,mg/g, ìg/g, mg, ìg, mg/mL, ìg/mL, mg Br/100g, g Br/100g, mg Br, g Br Sample type: Liquid or solid (external dissolution/extraction) Titration vessel: Operating volume between 100-200mL. Generator electrode: With diaphragm Sensor Type: HI76330 dual platinum pin polarization electrode Polarization Current: 1, 2, 5, or 10 μA Voltage Range: 2 mV to 1100 mV Voltage Resolution: 0.1 mV End point criteria: Fixed mV persistence, relative drift stop, or absolute drift stop Results static: Standard, mean deviation
