Overview

The KV-500A petroleum product kinematic viscosity tester features a digital display of temperature and a 4-channel timer. The applicable standard is GB/T265 ASTM D445, which is suitable for determining the kinematic viscosity of liquid petroleum products. The instrument is based on the MCS-51 series microcontroller and uses precision platinum resistance as the temperature measuring element to achieve high-precision constant temperature control. Its characteristics are reliable operation, easy operation, and high precision. It is widely used in departments such as petrochemicals, power, railways, and scientific research, and is an equipment for oil analysis and quality inspection.

KV-500A typePetroleum product kinematic viscosity testerCompliant with the national standard GB/T265-88 "Determination of Kinematic Viscosity of Petroleum Products and Algorithm for Dynamic Viscometers", it is used to determine the kinematic viscosity and dynamic viscosity of liquid petroleum products (referring to Newtonian liquids) (dynamic viscosity can be obtained by multiplying the measured kinematic viscosity by the density of the liquid at the same temperature), with the unit of m/s2, usually used in practice in mm/s2. This instrument is also applicable to the methods specified in ISO3104, ASTM D445, and IP71 standards.Suitable for determining the kinematic viscosity of liquid petroleum products.

KV-500A typeThe working principle isNewtonian liquids refer to liquids where the ratio of shear stress to shear rate is a constant, and also where the shear stress and shear rate of a liquid are independent of viscosity.The instrument is based on the MCS-51 series microcontroller. After setting a constant temperature point, the instrument automatically heats up, maintains a constant temperature, and turns on the stirring motor. When the temperature is constant, the test can be carried out according to the method specified in GB/T265-88 standard.
