Volumetric Karl Fischer Titrator

Instrument Introduction:

Karl Fischer titration (volumetric titration method) is a precision analytical instrument based on the classical Karl Fischer reaction principle, specifically designed for accurately determining the moisture content in samples. The volumetric method calculates the water content directly by the volume consumed by the titrant, with efficient operation and accurate and reliable results.

Detection Principle:

The Karl Fischer method is based on the quantitative reaction of I ₂, SO ₂, and water. The instrument uses the permanent stop titration method to indicate the endpoint, and the electrode monitors the sudden change in current during the titration process to accurately determine the reaction endpoint, thereby calculating the sample moisture content based on the consumed Karl Fischer test dose.

Applicable Standards: 

The measurement accuracy of this Karl Fischer titration moisture meter (volumetric titration method) complies with the provisions of JJG 1154-2018 "Calibration Regulations for Karl Fischer titration Moisture Meters".
