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 more >

KN-2983 Low Temperature 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 more >

KN-4603 Inherent Viscosity Apparatus for PET Polyester

The inherent viscosity is determined by measuring the flow time of a solution of known polymer concentration and the flow time of the pure solvent in a capillary viscometer at a fixed temperature. The inherent viscosity value is calculated from the flow time valuesRead more >

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 more >

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 more >

KN-1092 Apparatus for Apparent Viscosity of Lubricating Grease

KN-1092 Apparatus for Apparent Viscosity of Lubricating Grease conforms to ASTM D1092 Standard Test Method for Measuring Apparent Viscosity of Lubricating Grease. This Test method covers measurement, in poises, of the apparent viscosity of lubricating greases in the temperature range from -54℃ to 38℃ (-65℉ to 100℉). Measurements are limited to the range from 25P to 100000P at 0.1s-1 and 1P to 100P at 15000s-1. Apparent viscosity versus shear rate information can be useful in predicting pressure Read more >

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 more >
