The WKT-C1 "Smart" Karl Fischer moisture analyzer is a fully automatic moisture analysis system jointly developed by VicoMeter's R&D department and the 53rd Research Institute of China North Industries Group. Using the volumetric principle, it measures moisture down to 10 ppm and determines solids, liquids, and powders within 30 seconds. Its RS232 port connects printers, balances, computers, and other peripherals; it stores 100 data sets; and its separate 7-inch capacitive touchscreen runs an embedded micro Windows system — powerful, with clear operation prompts and flexible user interaction. In 2010, with help on ultra-precision displacement measurement from the State Key Laboratory of Precision Measurement Technology and Instruments at Tsinghua University, the WKT-C1 titration system was further improved, raising its measurement accuracy once again. The WKT-C1 complies with multiple national and international moisture standards and with pharmacopoeia requirements and is widely used in chemicals, petroleum, pharmaceuticals, power, food, batteries, plastics, research, and testing.
