Ksz7500 type automatic acid value tester for petroleum products (BTB method)





Instrument features:



◆ with high precision photoelectric integrated design, it can accurately detect the acid value of transformer oil, turbine oil, fire resistant oil, diesel oil, oil refining, gasoline and other petroleum products;



◆ adopting heating reflux method and built-in circulating water cooling system to realize automatic cooling reflux without running water and save water resources;



◆ it fully complies with the requirements of GB / t264-1983 and GB / t7599-1987 standards, and can automatically add samples, automatically heat, automatically titrate, automatically judge the end point of titration, automatically clean the pipeline, and automatically print the measurement results. The whole test process is fully automatic, with high degree of automation and no need for manual intervention;



◆ the unique self calibration system can calibrate the concentration of neutralization solution, automatically calibrate and deduct the acidity value (blank value) of ethanol itself, calibrate the measurement accuracy of neutralization solution, greatly reduce the measurement error caused by various factors, and improve the measurement accuracy;



◆ 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;



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



◆ the instrument has the characteristics of anti voltage fluctuation, environmental electromagnetic interference, strong electromagnetic compatibility (EMC), and conforms to iec801 standard.
