SF-1D type Trace moisture tester
The instrument uses - Karl Fischer coulometry (card's power method) water samples overcome - Karl Fischer titration accuracy of the instrument is low reagent consumption big, complicated operation and other shortcomings, the instrument uses a large electrolytic current and controls the current through the electrolysis titrant (iodine), so that the agent can be repeated continuous use, direct digital display of measurement results with analysis of short (typically 1 minute a result), simple operation, high accuracy, automaticity and other characteristics, the instrument used in petroleum, chemical production process and product moisture measurement; determination of oil-filled electrical equipment insulating oil in water; pharmaceuticals, pesticides, food, explosives, paints, lacquers, mineral raw materials and other substances in water Determination.
