product overview
WKT-A8 fully automatic Karl Fischer moisture analyzerThe principle of Karl Fischer Coulomb method (coulometric method) is used to quickly determine trace moisture in samples. The moisture content can be measured as low as 1ppm (0.0001%), and the trace moisture of solids, liquids, and powders can be determined within 1 minute. The instrument has a built-in printing function and can store 600 sets of data, which can be queried and printed in real time!WKT-A8 fully automatic Karl Fischer moisture analyzerThe biggest feature is the ability to automatically add reagents and discharge waste liquids, which can avoid direct contact between operators and reaction reagents, as well as the impact of volatile components of reagents on the human body. The instrument complies with multiple national and international moisture determination standards and has four built-in moisture calculation formulas, which can meet the needs of moisture determination in various industries. It is widely used in industries such as chemical, petroleum, pharmaceutical, power, food, scientific research, and testing.
