I. Overview
Kinematic Viscosity: At a constant temperature, determine the gravity flow under a certain volume model, through a calibrated glass capillary viscometer, the flow of the capillary viscometer constant with time, and the kinematic temperature of the product is used to measure the viscosity of the liquid
HZ1821 petroleum kinematic viscometer. The instrument meets the requirements of the national standard GB/T265 "Petroleum Products Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method". It can place four sticks of viscosity and conduct experiments at the same time, and can also be used as a high-viscosity constant temperature water bath for other experiments. It adopts color LCD large-screen English display, no logo button, and uses precision platinum resistance PT100 for temperature measurement, which can be set arbitrarily from 10 to 100°C. The main and auxiliary heaters are automatically switched, and the constant of the capillary can be stored when the power is turned off. Automatic calculation of viscosity value, this product also complies with ASTM D445.
