Instrument Introduction:

One Overview

This product is a research achievement of Zhejiang University and is at the forefront of domestic testing technology indicators and performance. Won the invention patent issued by the China National Intellectual Property Administration (patent number:ZL 97 1 00943.0）. It is a domestically produced scientific instrument recommended by the China Instrumentation Association and the Analysis and Testing Association.

A .Main purpose and scope of application

Capacity titration Karl Fischer（Karl Fischer）Method is an accurate method for determining the moisture content of substances in various chemical methods, and has become a commonly used analytical method internationally.ZKF1Karl Fischer water analyzer is a sophisticated automatic analysis system that uses Karl Fischer volumetric titration to determine water content. It is a very suitable conventional analytical instrument.

This instrument can be used in principle for the determination of moisture content in drugs, organic chemicals, inorganic chemicals, petrochemicals, fertilizers, pesticides, dyes, food, beverages, surfactants, cosmetics, fibers and other objects.

Due to the diverse characteristics of the tested substance, a solvent that can dissolve the substance should be selected for actual measurement.

B . Product Features
