NF-1 NF-2 Differential Sticking Tester
NF-2 type of adhesion coefficient tester

Overview
The instrument is an analog of the test analysis equipment, mainly for the monitoring of deep drilling and borehole drilling fluid in the coefficient of friction between, for the timely processing of drilling fluids to improve their lubricity and prevent the occurrence of sticking, to ensure fast, secure and reliable data to provide accurate drilling. With a compact, high precision, convenient operation. Widely used in various fields, research institutes, laboratories and other departments.

Model and specification

NO Model and specification NAME Different configurations at Features
1 NF-1 Adhesion coefficient tester Components without the pressure tube
Adhesion adhesion between the
plate and the filter cake with
additional bar by human pressure.
2 NF-2 Adhesion coefficient tester Pressure tube components
Adhesion between the adhesion
and cake plate by air pressure
acting on the cylinder pressure
to put pressure on the adhesive disc
