The VicoMeter WKT-A1 Entry-Level Karl Fischer trace moisture analyzer uses the coulometric Karl Fischer (coulometry) principle to rapidly measure trace moisture, detecting water down to 1 ppm and determining trace moisture in solids, liquids, and powders within one minute. It offers a friendly interface with a 128×64 blue LCD and full Chinese menus. The detection circuit uses digital processing to overcome the temperature drift and power-supply fluctuation that troubled traditional instruments, improving testing precision and sensitivity. The whole instrument is built with a relay-free process design, eliminating the hidden risk of relay contact oxidation and extending service life. It is widely used in chemicals, petroleum, pharmaceuticals, power, food, research, and testing.
