Acid number titration

Säurezahl-Titrator, Neutralisationszahl, TAN

The acid number (or "neutralization number") is used as an expression for the freshness of fats, e.g. in the food industry.

The Acid Number Titrator is designed for the determination of free fatty acids in oils and fats. Its operating mode complies with IEC 62021-1:2003 and ASTM D664-95 standards for mineral oils.


The acid number of oils and fats is an indication of their age and quality. The device is suitable for analysis of

  • transformer oils
  • natural and artificial fats
  • mineral oil products
  • lubricants
  • food fats (e.g. olive oil, butter)


  • Complete measuring system for the determination of TAN (Total Acid Number)
  • Fully-automatic volumetric titration
  • Special software for precise control of the titration parameters, e.g. adaptation to slow reaction rate
  • Preset measurement method allows an immediate start
  • The result output can be adjusted to your needs by using a formula generator
