Description
The Karl-Fischer method is a classical and most reliable method for the determination of trace moisture in different substances. The Karl-Fischer Coulometric method, is more suitable for the determination of substances with an absolute water content of less than 100 μg in the incoming sample. We have successfully applied this method with our Carl-Fischer trace water tester, which is particularly suitable for the determination of trace water in samples. Trace water in samples can be accurately determined by using appropriate operating methods.
Applicarion
Coulometric trace water tester is based on the hardware of microcontroller control and successfully incorporates our understanding of physical and chemical phenomena related to the measurement process. Its fast analysis speed, high accuracy, direct display of measurement results, multiple analysis methods can be freely set by you, and you can print records and solidify the operation time, making it a highly efficient and fully automatic precision analyzer.
