1、 Purpose:

WS-3Micro moisture analyzer based on Karl-The principle of Fischer titration uses advanced microcomputer circuits to determine the content of trace water in liquids, solids, and gases with different properties. For solids that are insoluble in reagents, as well as substances that react chemically with reagents or easily contaminate electrodes, corresponding solid and liquid samplers can be used for indirect measurement.

2、 Characteristics

This instrument has the advantages of high measurement accuracy, fast analysis speed, wide range of use, stability and reliability, simple operation, and has functions such as fault self checking and printing operation time. Widely used in industries such as electricity, petroleum, chemical, pesticide, and medicine. The sample determination process is automatically controlled by the instrument, including stirring and measurement60Automatically completed in about seconds, directly displaying the measurement results; Fully sealed titration cell bottle, avoiding contact between reagents and people, and also avoiding the influence of environmental humidity;
