Follow on Google News | GD-251 Total Base Number TesterGD-251 Total Base Number Tester is suitable to determine base number of petroleum products and additive.
By: Chongqing Gold ME Equipmnet Co.,Ltd. GD-251 Total Base Number Tester is designed and made as per the Industry Standard of Petrochemical SH/T0251-93 “Test Methods for Base Number of Petroleum Products”. It is composed of ZD-2 Automatic Potential Titrimeter and DZ-1 Titration Device. It is suitable to determine base number of petroleum products and additive. It 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. Technical parameters 1. Volumetric analysis: (1) Titration condensation: (2) Controlling accuracy: ≤±0.02ml; 2. Automatic acid titration: (1) Titration condensation: (2) Controlling accuracy: ≤±0.1pH; 3. Automatic potential control: (1) Titration condensation: (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: 9. Relative humidity: ≤85% End
