Instrument Overview Technical Parameters Performance characteristics
The instrument is designed and manufactured in accordance with the standards of the People's Republic of China GB/T7304 Determination of Acid Number of Petroleum Products and lubricants by Electric Potential Titration, GB/T 18609 Determination of Acid Number of crude oils by Electric Potential Titration, industrial standard NB/SH/T0836 Determination of Acid Number of insulated oils by Automatic Electric Potential Titration, etc. It is suitable for testing the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant fuel, diesel oil, gasoline, etc. It can be widely used in petroleum Chemical, electric power, quality inspection, scientific research and other industries.
1. Operating power supply: 220 V ± 10%, 50 Hz
2. Potential measurement range: (0~± 2000) mV;
3. Fundamental error of the electronic unit: 0.1% ± 0.001 mV of full reading, with a minimum volume of 0.001 mL;
4. Input impedance: Ri ≥ 1 × 1012 Ω;
5. Buret volume: 10 mL (10 to 50 mL optional);
6. Buret accuracy: ± 0.01% (F · S);
7. Determination range (in PH): 0~20;
8. Precision: in accordance with GB/T1792, SH/T162, GB/T264, ASTM D664, and other relevant standards for potential determinations;
9. Environmental temperature: 5 ° C~35 ° C
10. Relative humidity: no more than 80%
1. The instrument has a high input impedance, ensuring the accuracy of the measured potential;
2. The instrument uses a 24 bit A/D converter to ensure the accuracy and linearity of the measured potential;
3. The imported (Swiss Wantong) exchange unit is adopted, and all components are processed from corrosion and oil resistant materials, ensuring the airtight and flexible nature of the Titration Unit and no leakage in long-term use;
4. The imported motor driving exchange unit is adopted, and the motor step angle is small (only 0.9 o), ensuring high accuracy and good repeatability of the volume of the Titration;
5. The software has the function of automatically screening the measured value of potential, smoothly the curve of Titration, and effectively filter false end points;
6. The software has the functions of automatically judging the end point and manually selecting the end point, and can automatically make necessary corrections to the end point volume to prevent improper setting of the parameters for the Titration, and can also be used as an effective Titration to report the results of the Titration;
7. Titration parameters are set flexibly and can be designed or configured for other purposes;
8. Titration results are automatically saved to the database for later inquiry;
9. The instrument can be connected to a printer to print the Titration Curve and Titration Results;
10. The working software is simple, intuitive, and very easy to learn;
11. Has a constant value addition function; With automatic cleaning function;
12. The number of end points can be set freely and can be used for the separate Titration of mixed ions;
