Which Standards Do Trace Moisture Analyzers Comply With?

The trace moisture analyzer is also known as the Karl Fischer moisture analyzer; related terms include moisture analyzer, moisture meter, moisture tester, and moisture measurement instrument. The Karl Fischer coulometric method precisely measures trace moisture in samples—liquids, solids, and others—based on Karl Fischer coulometric titration, and is widely used in electric power, petroleum, chemicals, pharmaceuticals, food, and solar panel cutting fluids.

VicoMeterThe WKT-A8 "fully automatic" Karl Fischer trace moisture analyzer uses the Karl Fischer coulometric (electrolytic) principle to rapidly determine trace moisture in samples, measuring moisture down to 1 ppm (0.0001%) and determining trace moisture in solids, liquids, and powders within 1 minute. The instrument has a built-in printer, can store 600 data records, and supports real-time query and printing! Its biggest advantage is automatic reagent addition and automatic waste discharge, keeping operators from direct contact with reagents and protecting them from volatile reagent vapors. The instrument complies with multiple national and international moisture measurement standards and has four built-in moisture calculation formulas to meet the moisture measurement needs of every industry. It is widely used in chemicals, petroleum, pharmaceuticals, electric power, food, research, and testing.

Application Fields：

Liquids—chemical industry: alcohols, ethers, esters, acids, alkanes, benzenes, amines, organic solvents, phenols, and other organic products suitable for Karl Fischer determination.

Petroleum and power industry: insulating oils, transformer oils, turbine oils, and other oil products

Pharmaceutical industry: pharmaceutical raw materials, etc.

Pesticide industry: emulsifiers, etc.
