Summary

The instrument uses potentiometric titration principle. Recording the titration of the electrode potential and the titration volume, find out the equivalence point and corresponding titrant volume, and thus obtained the sample pH value. This instrument can accurately detect the acid value of transformer oil, turbine oil, anti oil, diesel, gasoline and other petroleum products；Widely used in chemical industry, electric power, oil and other industries, it’s the ideal products to current meter acid number of petroleum products. Standard：GB/T264 Determination of acid number、GB7599-87 Determination of acid number in transformer and turbine oils in service（BTB）、GB/T7304-2000. GB/T 18609-2001. D664—01.ASTM D664-2011)
