MS-203A Fully Automatic Water-Soluble Acid Tester

This instrument (utilizing the colorimetric method) is designed and manufactured in accordance with the People's Republic of China National Standard GB/T 7598-2008 ("Determination of water-soluble acids in transformer oil during service") and other relevant standards. Featuring a large LCD screen and microprocessor control, it automatically performs functions such as heating, constant-temperature control, oscillation, sampling, testing, cleaning, and printing based on user-defined parameters. It can process 1 to 6 samples in a single run, significantly reducing testing time for the user.

Instrument Features

1. Designed and developed in compliance with the GB/T 7598-2008 standard, this fully automated instrument accurately measures water-soluble acids in petroleum products such as transformer oil, turbine oil, and fire-resistant oil.

2. Easy operation via a color touchscreen LCD.

3. Uses the colorimetric method to determine pH values.

4. High level of automation: simply inject the oil and water according to standard specifications, and the instrument automatically completes heating, oscillation, settling, oil-water separation, color development, colorimetric analysis, and the display/printing of results.

5. Capable of processing and sequentially testing 1 to 6 samples in a single batch.

6. Integrated design for an aesthetically pleasing appearance; large 7-inch screen for simple and convenient operation; built-in reagent compartment keeps needles shielded from the air (preventing contamination and enhancing safety for operators); customizable PC software system; high-precision physical sampling mechanism ensures accurate test results.
