Kinematic Viscosity Tester

The HZ1151 fully automatic apparent viscometer (CCS) complies with technical specifications such as GB/T6538-2010 and ASTM D5293; it is suitable for testing the low-temperature dynamic viscosity index of engine oil. The instrument can measure the apparent viscosity of oil at a temperature of -35°C to -5°C with an interval of 5°C. 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 a shear stress of about 500 to 20000 mPa.s and a shear rate of 105 to 104 S-1 at -5°C to -30°C. The instrument uses fully automatic temperature control equipment, users only need to operate on the color touch screen to quickly and easily perform testing and analysis.

The device is controlled by the single-chip microcomputer , with a high degree of automation, automatic discharge functions. It is a test instrument of high precision, simple, direct way to achieve fast transformer measurement.

The Kinematic Viscosity Tester operates on the principle of measuring the time it takes for a specific volume of liquid to flow under gravity through a calibrated capillary tube. This time is then used to calculate the kinematic viscosity, which is expressed in centistokes (cSt). The tester is equipped with advanced temperature control systems to ensure that measurements are taken at consistent and precise temperatures, as viscosity is highly temperature-dependent.
