Karl fischer water content tester(with cassette furnace) ZWS301

♦High performance ARM processor with large data storage capacity；

♦Running fast and stable performance;

♦Excellent anti – jamming performance.

Product Introduction

The instrument by Karl Fisher coulomb titration method, can reliably on liquid, gas and solid samples for trace moisture determination. When testing, for insoluble solid reagent and easy contamination of the electrode and reagent material can be equipped with corresponding solid, gas and liquid injector for indirect determination, is a kind of highly efficient, fully automatic analysis instrument. Widely used in electric power, petroleum, chemical, pharmaceutical, railway, environmental protection, scientific research institutions and other industries.

The disposable sample bottle can be used to take samples for heating and vaporization. It is suitable for water vaporization devices of standard weight solid or quasi-solid samples, such as plastic particles, carbon powder, inorganic salts, battery separators, liquid crystals, coatings, food, medicines, etc. Working principle: The water in the sample is vaporized by the heater, and the water is carried into the reaction bottle with high-purity nitrogen as the carrier gas to participate in the Karl Fischer reaction , thereby obtaining the water content in the solid.

Functional Characteristics

1.Micro moisture meter is a new development of the determination of trace water analysis instrument, the instrument uses high resolution color touch LCD display, convenient man-machine conversation, intuitive and easy to operate;

2.The instrument adopts the high performance ARM processor with large data storage capacity, running fast and stable performance and excellent anti – jamming performance, which has outstanding advantages of high detection speed and high precision;

3.The instrument has the fault diagnosis function, the end of the test, display and print results. Instrument has potential is measured dynamic curve indicating function, makes the test more intuitive; instruments and data storage capacity up to store 500 data records;

4.The instrument has delay measuring function, is very effective in the testing of lower moisture content of specimen; 5.The instrument adopts the sliding touch control the stirring speed control;

6.Water content calculation formula contains calculated according to the volume and weight of the key parameters of various algorithms;

7.Testing process, such as the need to modify the formula for calculating the related parameters, can be modified in a timely manner and does not affect the measurement of moisture content, moisture content is in accordance with the revised parameters calculated to facilitate the users.
