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.
