LogicOil TAN TBN Titrator
LogicOil’s TAN/TBN titrator provides Total Acid Number (TAN) or Total base Number (TBN) determination of oils and fats.

Determination of TAN or TBN in Oils & Fats
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 quantity of acid which can be neutralized by additives in mineral oils.
The device is conform to standards IEC 62021-1, ISO 3771, ASTM D 664, ASTM D 2896, 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.
Advantages
- 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
Details
The TAN/TBN Titrator consists of;
- an automatic volumetric titrator with potentiometric
pH indication and integrated temperature sensor
a titration vessel with stirrer unit
The determination of TAN/TBN value is based on
- an acid-base-titration in an anhydrous medium
- a precise indication by an electrode filled with anhydrous ethanol/LiCl
Steps of the analysis are
1. Calibration of the electrode
2. Determination of the blank value
3. Standardization of the titration solution
4. Titration of oil samples
