YH-265A type petroleum product kinematic viscosity tester

Short Description:

This instrument complies with GB265 "Methods for Determination of Kinematic and Kinetic Viscosity of Petroleum Products" and ASTM D445 standards, suitable for measuring kinematic and kinetic viscosity in liquid petroleum products (specifically Newtonian fluids). The method involves determining the viscosity by measuring the time required for a fixed volume of liquid to flow through a calibrated glass capillary viscometer under gravity at a constant temperature. The viscosity is calculated as the product of the capillary constant and flow time at that temperature. Widely used across industries including electrical oil, power generation, chemical engineering, railway systems, and scientific research.

Main Features:


1, using advanced single chip microcomputer intelligent temperature control, temperature control accuracy 0.02℃;
2. Chinese LCD screen display, timely display the instrument's temperature, time, parameters and other working status;
3, 4 viscometer test hole design, unique modular technology, can be measured in low viscosity or high viscosity range;
4. The instrument automatically calculates the kinematic viscosity value and test average value, and automatically prints and stores the measurement results;
5. The timing is 0.1 seconds to 999.9 seconds, and the temperature range of room temperature-120.00 degrees can be set arbitrarily;
6. The double-layer constant temperature glass bath has an outer organic glass insulation cover, so the temperature distribution in the bath is uniform and the temperature control effect is good;
