Based on the Hoeppler measurement principle, simple and accurate dynamic viscosity measurements are performed on transparent Newtonian fluids. The core concept is to measure the actual time required for a falling ball to descend from a sample tube tilted at a working angle under the action of gravity.
The sample tube is assembled on a central bearing that allows the sample tube to quickly flip 180 degrees, allowing for immediate repeated measurements. The measurement results are based on the average time it takes for the falling ball to land in three measurements. Convert the time reading into the final viscosity value using another conversion formula
A set of six drop balls is used for various industrial QC controls and research institutions, and the easy-to-use and simple method of recording time measurements ensures meaningful test results.
Used in conjunction with the Brookfield constant temperature system to quickly control the temperature of the sample, resulting in more accurate and highly reproducible results
