Engine oil apparent viscosity tester applicable standard: GB / T6538 ASTM D5293 The instrument mainly tests the low temperature power viscosity index of engine oil, using contemporary advanced technology, set mechanical, optical electronics and computer technology in one, temperature measurement, constant temperature control. Temperature control is accurate and stable. The engine oil apparent viscosity tester is designed with reasonable structure, stable performance and simple operation.

Fully automatic engine oil borderline pumping temperature measuring instrument Applicable standards: GB/T9171, ASTM D3829, fully automatic engine oil borderline pumping temperature measuring instrument adopts modern advanced technology, integrates mechanical, optical electronics and computer technology into one, for temperature measurement, Constant temperature control. Temperature control is precise and stable. The fully automatic engine oil boundary pumping temperature measuring instrument has reasonable structure, stable performance and simple operation, and is an ideal analytical testing equipment.

The automatic high-temperature high-shear viscometer mainly measures the apparent viscosity of lubricating oil at high temperature and high shear rate. The test principle is to make the sample from the capillary under the pressure of nitrogen (carbon dioxide) under the test condition of 150 °C. The viscometer flows out, and the apparent shear rate of the capillary viscometer reaches a certain apparent viscosity from the outflow time and pressure of the sample, and the viscosity of the oil corresponding to the measured pressure is corrected by the curve of each viscometer.

Instrument meet the requirements of SH / T 0361 standard design and production, mainly used to assess the rail oil lubrication adhesive-sliding performance, the specific index is static-dynamic friction coefficient difference, the smaller the difference, the lubricant viscosity-sliding performance, the better, is used to evaluate the rail oil, the use of rail oil again later has a good guidance and evaluation effect.
