Titramax VT TAN/TBN

TAN/TBN Titrator
Titramax VT TAN/TBN

Determination of  total acid or base number of oils and fats

The Titramax VT TAN/TBN is suitable for determination of Total Acid Number (TAN) or Total Base Number (TBN) of oils and fats. The acid number expresses the quantity of base required to neutralize all acidic constituents of the sample. It is a quality feature for freshness of oils and fats. The base number indicates the quantity of acid which can be neutralized by additives in mineral oils.

The device is conform to standards ASTM D 664, DIN 51558, IEC 62021-1, Pharmacopoeia (TAN) and ASTM D 2896, ASTM D 4739, ISO 3771, UOP 269 (TBN).

The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the oil sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms.

The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in mg KOH/g oil or several other units.


The value of TAN/TBN is an indication of age and quality of oils and fats. 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/TBN
  • Fully-automatic volumetric titration
  • Precise adjustment of the titration parameters by control algorithms
  • Preset measurement method allows an immediate start
  • The result output can be adjusted to your needs by using a formula generator
