The Titramax VT TAN/TBN is suitable for determination of Total Acid Number (TAN) or Total Base Number (TBN) of oils and fats. Th 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 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 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 algorithm
