This instrument is intended to measure the friction coefficient of the filtration cake formed in the drill flush fluid. Such measurements are performed in field laboratories and at drilling rigs to estimate the efficiency of lubricating additives and operative intervention in the process of drilling in abnormal conditions.
Why this particular design? Because it supersedes previous models (with manual and electrical drives), combining their functions and providing better stability of readings (it is possible now to change the lifting speed). Moreover, as distinct from similar products (having scales that cannot be certified without special devices), its performance can be checked by the operating personnel! It is essential for all products having the word “instrument” in their name. The most popular model!
