Acid Value Meter

The acid value measuring instrument uses the principle of neutralization reaction to titrate free acids in samples with a standard alkali solution, determining the endpoint via potentiometry or indicators. It is used to measure the acid content of substances such as oils and resins, and to monitor changes in the acidity of raw materials and products in chemical production and quality inspection.
Selection
When selecting, consider the compatibility of sample characteristics with detection methods; oily samples are suitable for potentiometric titration. Pay attention to the titration accuracy and minimum detection quantity of the instrument, which should include an automatic cleaning function. Verify the requirements for repeatability and error according to standard specifications to ensure data reliability.
