KN-7279C Automated Houillon Viscometer
KN-7929C Automated Houillon Viscometer conforms to ASTM D7279 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer. Many petroleum products and some non-petroleum products are used as lubricants in the equipment, and the correct operation of the equipment depends upon the appropriate viscosity of the lubricant being used. Additionally, the viscosity of many petroleum fuels is important for the estimation of optimum storage, handling, andRead

KN-2983 Low Temperture Brookfield Viscometer
The low-temperature, low-shear-rate viscosity of automatic transmission fluids, gear oils, torque and tractor fluids, and industrial and automotive hydraulic oils are of considerable importance to the proper operation of many mechanical devices. Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service. This test method is used in a number of specifications.Read

KN-5293 Automated Cold Cranking Simulator (CCS) Viscosity Apparatus
The CCS apparent viscosity of automotive engine oils correlates with low temperature engine cranking. CCS apparent viscosity is not suitable for predicting low temperature flow to the engine oil pump and oil distribution system. Engine cranking data were measured by the Coordinating Research CouncilThe measurement of the cranking viscosity of base stocks is typically done to determine their suitability for use in engine oil formulations. A significant number of the calibration oils for this metRead

KN-4684 Yield Stress Apparent Viscosity of Engine Oils Apparatus
An engine oil sample is held at 80°C and then cooled at a programmed cooling rate to a final test temperature and held for a specified time period. At the end of this period, a series of increasing low torques are applied to the rotor shaft until rotation occurs to determine the yield stress, if any is exhibited. A higher torque is then applied to determine the apparent viscosity of the sample.Read

KN-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS)
High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS) covers the laboratory determination of high-temperature high-shear (HTHS) viscosity of engine oil at a temperature of 150℃ using a multicell capillary viscometer containing pressure, temperature, and timing instrumentation. The shear rate for this test method corresponds to an apparent shear rate at the wall of 1.4 million reciprocal seconds (1.4 3 106s-1).This shear rate has been found to decrease the discrepancy between thisRead

KN-2171 Apparatus for Viscosity of Asphalts
KN-2171 Apparatus for Viscosity of Asphalts conforms to ASTM D2171 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer. The viscosity at 60℃ characterizes flow behavior and may be used for specification requirements for cutbacks and asphalt binders. This time is measured for a fixed volume of the liquid to be drawn up through a capillary tube by means of vacuum, under closely controlled conditions of vacuum and temperature. The viscosity in Pascal-seconds is calculated Read
