Overview
The entry-level Karl Fischer moisture analyzer WKT-A1 uses the principle of Karl Fischer Coulombic method (coulometric method) to quickly determine trace moisture in samples. The moisture content can be measured as low as 1ppm, and it can determine the trace moisture content of solids, liquids, and powders within 1 minute. The human-machine interface is friendly, with a 128 * 64 blue screen LCD display and a fully Chinese menu. The detection circuit uses digital processing technology to overcome the interference of temperature drift and power supply voltage fluctuations in traditional instruments during the testing process, improving the accuracy and sensitivity of the testing.
