Ksz7506 type automatic acid value tester for petroleum products

(Patent No.: zl201120074332.6 \ zl201310250142.9 \ zl201320362086.3)





Instrument features:



1. With the high precision photoelectric integrated design, the acid value of transformer oil, turbine oil, fire resistant oil, hydraulic oil, diesel oil, gasoline and other petroleum products can be accurately detected;



2. Adopting the principle of extraction neutralization titration, highly intelligent design, large screen LCD display, Chinese menu operation, using microcomputer control to automatically complete the functions of adding liquid, titration, stirring, judgment of titration end point, cleaning of automatic pipeline, printing results, etc. under normal temperature, the whole test process is fully automatic, with high degree of automation, without manual intervention;



3. The unique self calibration system can calibrate the concentration of the neutralizing liquid, automatically calibrate and deduct the acidity value (blank value) of the extraction liquid itself, calibrate the measurement accuracy of the neutralizing liquid, greatly reduce the measurement error caused by various factors, and improve the measurement accuracy;



4. The unique air pressure titration system adopts high-precision optoelectronic coupling measurement system, which effectively avoids the defects such as broken tube, easy to produce bubbles and large measurement error under the pump pressure titration mode such as peristaltic pump;



5. The unique phosphoric acid fire-resistant oil detection system can effectively detect the acid value of phosphoric acid fire-resistant oil;



6. The concentration of neutralizing solution can be used in the range of 0.02-0.05mol/l, and the concentration of neutralizing solution can be calibrated automatically;





7. The unique "one key cleaning" function of the pipeline, and the forced cleaning function of shutdown, no need to worry about the blockage of the pipeline, and improve the service life of the pipeline.



8. The unique design of delivery pipeline for extraction and neutralization liquid prevents the reagent from contacting with air during use, avoiding the influence of solvent volatilization and acid gas in the air; the user does not touch the solvent by hand, reducing the harm of organic solvent and chemicals to human body;



9. The instrument can select the number of test samples according to the user's needs. The samples can be tested in groups freely, which is convenient and efficient.



10. The instrument has the characteristics of anti voltage fluctuation, environmental electromagnetic interference and strong EMC capability, which conforms to iec801 standard.



11. The shell is made of new ABS anti-static material and streamlined design, with exquisite appearance and structure design, beautiful appearance, comfortable operation and convenience.



12. Powerful data query and processing function, can store 200 experimental data, all kinds of experimental information at a glance.
