GD-251 ASTM Total Base Number (TBN) Tester

Ⅰ.Purpose:

GD-251 ASTM Total Base Number (TBN) Tester is designed and made as per the Industry Standard of Petrochemical SH/T0251-93 “Test Methods for Base Number of Petroleum Products”.

GD-251 ASTM Total Base Number (TBN) Tester is composed of ZD-2 Automatic Potential Titrimeter and DZ-1 Titration Device.

GD-251 ASTM Total Base Number (TBN) Tester is suitable to determine base number of petroleum products and additive. The TBN Tester determines and calculates base number of sample based on acid-alkali neutralization principle, perchloric acid potentiometric titration methods, and potential changes to detect end point.

Ⅱ.Technical parameters:

1. Volumetric analysis:

(1) Titration condensation: 0.1 N;

(2) Controlling accuracy: ≤±0.02ml;

2. Automatic acid titration:

(1) Titration condensation: 0.1 N;

(2) Controlling accuracy: ≤±0.1pH;

3. Automatic potential control:

(1) Titration condensation: 0.1 N;

(2) Controlling accuracy: ≤10mV;

4. Temperature compensation:

(1) Manual compensation;

(2) 5~60°C;

5. Preset adjustment range of end point: pH 1 to 13 or ±100~1300 mV;

6. Preset controlling range for titration: 1~3 pH or 100~300 mV from end point;

7. Power supply: AC 220V±10%, 50 Hz;

8. Ambient temperature: 0~35°C;

9. Relative humidity: ≤85%;
