| This instrument adopts potentiometric titration, records the titration of the electrode potential and the titration volume, finds out the equivalence point and corresponding titrant volume, and thus obtains 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. It is widely used in chemical industry, electric power, oil and other industries, it’s an ideal product to test the acid number of petroleum products. |
