Automatic Apparent Viscosity Measuring Instrument NT ～ -70℃ Engine Oil ASTM

Product Specification

SH110 Automatic Apparent Viscosity Measuring Instrument (CCS)

SH110 automatic apparent viscosity meter (CCS) conforms to GB/T6538-2022, ASTM D5293 and other technical specifications;Suitable for testing the low temperature dynamic viscosity index of engine oil.The instrument can measure the apparent viscosity of oil at temperatures ranging from -35℃ to -5℃ with an interval of 5℃.It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.

It is suitable for measuring the apparent viscosity of engine oil at -5~-30℃ under the condition of shear stress of about 1200 ~ 20000 mPa. S and shear rate of 105~104 s-1.The instrument adopts automatic temperature control equipment, users only need to operate on the color touch screen can be convenient for testing and analysis.

Apparent viscosity: Apparent viscosity is a physical concept that refers to the quotient obtained by dividing the corresponding shear stress by the shear rate at a certain velocity gradient. It is just a relative rough comparison of the quality of fluidity. True viscosity should be a part of irreversible viscous flow, and apparent viscosity also includes the reversible high elastic deformation part, so apparent viscosity is generally smaller than true viscosity. The apparent viscosity can be further divided into shear viscosity and tensile viscosity. The apparent viscosity may be higher than the true viscosity or lower than the true viscosity. On the engine oil, he can predict faults caused by insufficient engine oil pumping performance.
