Automatic acid tester
Product profile
The CHK-7599 automatic acid value tester for petroleum products is developed and produced according to GB/ T264-1983GB / T7599-1987 standard, the high precision optoelectronic integrated design is adopted, the acid value of transformer oil, steam turbine oil, anti-fuel oil, diesel oil, gasoline and other petroleum products can be accurately detected. Can be widely used in power, petroleum, chemical, commodity inspection and scientific research and other departments.
Functional characteristics
- Using extraction neutralization titration principle, highly intelligent design, large screen liquid crystal display, Chinese menu operation, using microcomputer control in.
- The functions of adding liquid, titration, stirring, judging the titration end point, cleaning the automatic pipe and printing the result are completed automatically at the temperature. The whole test process is self-contained.
- Dynamic, high degree of automation, no manual intervention;
- The unique self-calibration system can calibrate the concentration of neutralizing liquid and automatically calibrate and deduct its own acidity value.
- The measurement accuracy of neutralizing liquid is calibrated, which greatly reduces the measurement error caused by various factors and improves the accuracy of measurement.
- The unique pneumatic titration system adopts the high precision photoelectric lotus root measurement system, effectively avoids the peristaltic pump and other pump pressure titration way under the pipe to break easily
- Broken, easy to produce bubbles, large measurement errors and other defects;
- The special detection system for phospholipid and anti fuel oil can effectively detect the acid value of phosphoric acid grease.
- The concentration of neutralization solution can be chosen between 0.02~0.05mol/L and can be calibrated automatically.
- Unique pipeline design of extraction liquid and neutralizing liquid, the reagent is not in contact with air during use, avoiding solvent volatilization and acidity in air
- The influence of gas; the user does not touch the solvent by hand, reducing the harm to human body caused by organic solvent and chemicals;
- The instrument can select the number of test samples according to the needs of the user, and the samples can be detected in groups freely.
- The instrument has the characteristics of resisting voltage fluctuation, environment electromagnetic interference, strong electromagnetic compatibility and so on, and conforms to the IEC801 standard.
- The shell adopts new ABS antistatic material, streamline design, the appearance structure design is exquisite, beautiful, the operation is comfortable, convenient;
- Powerful data query and processing functions, can store 200 experimental data, all kinds of experimental information at a glance;
- Equipped with RS232 communication interface, can be connected with the computer, send detection data, data processing, etc., high degree of automation.
