Oil pH value testerDetailed Introduction

Oil pH value testerThe instrument adopts the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, the equivalent point and corresponding volume of the standard titration solution can be identified to determine the pH value of the sample.This instrument is suitable for testing the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel, gasoline, etc. accurately according to regulations; Widely used in industries such as chemical, power, and petroleum, it is an ideal replacement product for the current acid value analyzer for petroleum products.Meet the standardsGB/T264Method for determination of acid value of petroleum productsTheGB7599-87Determination method for oleic acid value of transformer oil and turbine oil during operation（BTBBranch)TheGB/T7304-2000Petroleum products and lubricants Determination of acid valueWaiting for standards.
