The VicoMeter WKT-C9 fully automatic Karl Fischer moisture analyzer uses the volumetric Karl Fischer principle to rapidly determine moisture down to 10 ppm, measuring solids, liquids, and powders within 30 seconds. Its built-in RS232 port connects printers, balances, computers, and other peripherals, and it stores 200 data sets with real-time query. A further upgrade of the Victor smart-series moisture analyzer, the C9 delivers a higher level of automation and precision. It complies with multiple national and international moisture standards as well as pharmacopoeia requirements and is widely used in chemicals, petroleum, pharmaceuticals, power, food, batteries, plastics, research, and testing.
