HK-265E Low temperature kinematic viscometer (semi-automatic type)ASTM D445 standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity). This test method specifies a procedure for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid.The range of kinematic viscosities covered by this test method is from 0.2 to 300 000 mm2/s at all temperatures. The precision has only been determined for those materials, kinematic viscosity ranges and temperatures as shown in the footnotes to the precision section.
Features 1.The apparatus consists of temperature controlling device, heating device, glass bath, bath lighting, dedicated cooling source, stirring device and viscometer clips. 2.The apparatus adopts digital display temperature controller, temperature control high precision, easy to adjust. 3.The apparatus adopts heating tube to heat, heat fast and can make the bath evenly warmed. 4.Using Dewar cold bath, transparency, good insulation properties. 5.H lighting equipment facilitate observation the sample of cold bath . 6.Imported compressor, refrigeration compressor technology, cooling capacity, cooling speed. 7.Using motor stirrer to make cold bath temperature constant. 8.Cold bath cover with two holes, comprises a new viscometer clip, easy to operate, while oil sample test can be done in parallel to improve efficiency. 9.Reasonable structure with beautiful shape and easy to operate.
