The TAN/TBN Titrator 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 quantityof acid which can be neutralized by additives in mineral oils.

The device is conform to standards IEC 62021-1, ISO 3771, ASTM D664, ASTM D2896, ASTM D 4739. 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.
