Under normal temperature, the microcomputer control automatically completes liquid addition, stirring, titration and end point judgment. The touch-type LCD screen is used to select all working parameters. The man-machine dialogue interface is simple and friendly, and the operation is convenient. The average analysis period of oil samples is about 2 minutes.

Starting from the actual use requirements, the division value of the electric meter is 0.1 ~ 0.001pH. If necessary, according to the current scientific and technological level, a more precise electric meter can be produced. However, due to structural and manufacturing reasons, the performance of commonly used electrodes cannot be perfect.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.voltage-tester.com\/uploads\/640-24.jpg\" alt=\"oil acid value tester\" class=\"wp-image-2300\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.voltage-tester.com\/uploads\/640-72.jpg\" alt=\"oil acid value tester\" class=\"wp-image-2301\"\/><\/figure>","protected":false},"excerpt":{"rendered":"<p>The detection of the&nbsp;acid value of insulating oil&nbsp;is a routine inspection item for power systems and oil-filled electrical equipment in industrial and mining enterprises.
