The automatic water soluble acid tester is designed and developed according to GB/T 7598 standard. The experiment is to mix and shake the sample with equal volume of distilled water under specified conditions, and take its water extract to determine its pH value through colorimetry. It is suitable for water-soluble acid of transformer oil, turbine oil, fire-resistant oil and other petroleum products.
Technical features:
Integrated design, single chip control.
The instrument has a high degree of automation.
LCD display, Chinese menu, easy to operate.
Automatically complete heating, oscillation, static discharge, oil-water separation, color development, colorimetry, display and print the measurement results.
