Automated Cold-Cranking Simulator ASTM D5293
Automatic simulator Of Cold-Cranking
This instrument conforms to GB/T6538-2010, ASTM D5293 and other technical
specifications; it is suitable for testing engine
It is suitable for testing the low temperature dynamic viscosity index of engine oil. The
instrument can determine the apparent viscosity of oil at -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~-35℃ under the
condition of shear stress about 2000~27000 mPa.s; and shear rate 105~104 S-1. The
instrument adopts fully automatic temperature control equipment and exquisite
human-computer interaction interface, so that users can easily and quickly use the
instrument for analysis. Meanwhile, the latest intelligent control system is adopted to
improve the stability and reliability of the instrument, making the temperature control
more accurate and the calculation precision higher, filling the gap of the domestic
petroleum analysis instrument
Product Description
Thermo-Oxidation Engine Oil Simulation Tester is used for thermo-oxidation engine oil simulation test.This test method covers the procedure to determine the mass of deposit formed on a specially constructed test rod exposed to repetitive passage of 8.5 g of engine oil over the rod in a thin film under oxidative and catalytic conditions at 285 °C.

Instrument advantages
1 using a split structure, the host and refrigeration are separated, which facilitates the
cooling of the refrigeration machine and reduces the impact of vibration on the test
results. Split cleaning device, also makes this wearing parts placed on the outside of
the host, failure, easy to quickly replace.
2 The machine adopts the way of 7 curves calibrated separately (B-value curve), each
temperature section has its own B-value parameters, which improves the accuracy of
use.
3WINDOWS system is used for software development, and the versatility of the
instrument makes the later use cost relatively low.
