Description

The pH meter of oil products adopts the principle of potentiometric titration. By recording the electrode potential and the titration volume during the titration process, the equivalence point and the corresponding volume of the standard titration solution are found, so as to obtain the pH value in the sample. The instrument can accurately detect the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel oil and gasoline. Used in chemical, electric power, petroleum, environmental protection, railway and other industries.

Standard: GB/T7304, GB7599, GB/T 18609, ASTM D664

Features

1. Windows operating platform, man-machine direct dialogue, convenient operation, with workstation function.

2. The titration curve is displayed in real time, and the titration curve, results and data are stored and printed.

3. Using imported titration unit, the instrument has higher measurement accuracy and better stability.

4, automatic cleaning, automatic fixed value adding liquid.

5. Automatically judge the end point, automatically filter out the false end point, and at the same time can manually select and judge the end point.
