HZCS-3 transformer oil acid tester is a fully automatic instrument using the extraction method to measure insulating oil acid value. It improves efficiency and accuracy while ensuring safety by reducing operator contact with samples and reagents.
Once the sample cups and extraction are placed, the instrument automatically performs blank titration, measurement, cleaning, result display, and printing. It can test 1–3 samples in one run, offering high efficiency.
With standard acid calibration, the user can adjust both the instrument and neutralizing solution at any time, avoiding errors caused by concentration changes. The tester also deducts the extract background value automatically, minimizing external influence. These features make the results accurate, stable, and reliable.
