With features like automatic reagent balance, touch functionality, and high precision components such as dual platinum electrodes, our titrators and analyzers ensure accurate results with minimal .
In these cases, we use the Karl Fischer Titration method—also known as Moisture by Karl Fischer (MKF) test. During the Karl Fischer Titration test, water is directly consumed by reaction with the titrant within the conditions of the reaction vessel. Thus Karl Fischer Titration is more selective for water than the traditional oven heating method.A Karl Fischer (KF) coulometric titrator is one of the most accurate methods. Unlike other techniques, it can trace low levels of free, emulsified and dissolved (which cannot be detected with other methods such as a crackle test). . The air conditioning system should be equipped with a moisture condenser. Also, a Karl Fischer titrator should .

what is karl fischer titration
This method for quantitative chemical analysis was developed by the German chemist Karl Fischer in the year 1935, Today, specialized titrators (known as Karl Fischer titrators) are available to carry out such titrations. Principle of Karl Fischer Titration The principle of Karl Fischer titration is based on the oxidation reaction between iodine . Karl Fischer titration. Karl Fischer (KF) titration for water determination was introduced back in the 1930’s, and to this day remains one of the most tried and trusted methods. It is a fast and highly selective method, which means that water, and only water, is determined. KF titration is based on the following two redox reactions.Digital Karl Fischer Moisture Analyzer With the interface provided with printers, these titrators have microprocessor based circuitry.
