Volumetric Moisture Meter

The volumetric moisture analyzer is based on the Karl Fischer chemical reaction, where a titration solution quantitatively reacts with the moisture in the sample, and the endpoint is determined by detecting the color change of the reagent. It is used to measure the moisture content in solids and liquids and is applied in quality control within the chemical, food, and pharmaceutical industries.
Selection
When selecting, consider matching the reagent type with the sample properties, ensuring the water content range falls within the instrument's measurement range, pay attention to titration accuracy and detection speed, evaluate anti-interference capability and operational complexity, and combine maintenance costs with regulatory compliance.

Application of Karl Fischer Micro Moisture Meter in Moisture Control of Lithium Battery Electrolyte
The Karl Fischer micro-moisture analyzer is based on the Karl Fischer titration principle, which measures trace moisture in lithium battery electrolytes through the quantitative reaction between iodine and water.
Selection Basis for Karl Fischer Titration: Volumetric vs. Coulometric Methods
There are two methods for Karl Fischer moisture titrators: volumetric and coulometric. The volumetric method calculates moisture by measuring the volume of a reagent with a known concentration that is consumed, making it suitable for samples with higher moisture content, such as those in the range of a few thousandths or more.
Karl Fischer Moisture Analyzer Determines Moisture Content in Powder Coatings
This article introduces the method of determining the moisture content in powder coatings using a Karl Fischer moisture analyzer. Excessive moisture content in powder coatings can affect the quality of the coating, leading to issues such as bubbles. The Karl Fischer method measures moisture through the quantitative reaction of iodine and sulfur dioxide, which is divided into volumetric and coulometric methods.
Determination of Non-Volatile Content: Comparison of Precision between Gravimetric and Volumetric Methods
This article compares two common methods for determining non-volatile content: gravimetric method and volumetric method. The gravimetric method involves evaporating the sample through heating and weighing the residue. It is simple, versatile, and suitable for most stable samples. The volumetric method is based on titration through chemical reactions, making it suitable for measuring specific components, although its method development is more complex.
Difference between halogen moisture analyzer and Karl Fischer moisture analyzer
The core difference between halogen moisture analyzers and Karl Fischer moisture analyzers lies in their measurement principles. Halogen moisture analyzers are based on the thermogravimetric method, while Karl Fischer moisture analyzers rely on titration principles, either volumetric or coulometric, which involve quantitative chemical reactions specifically targeting water molecules.
