1 ABOUT YOUR GAUGE
The Elcometer 108 Hydraulic Adhesion Tester is used to measure the adhesion between a coating and its
substrate.
During the application of a coating, there are many variables that affect the final finish and performance.
These include surface preparation, cleanliness and contamination, the coating system, the compatibility of
the different coating layers and the climatic conditions during the process.
There are two versions of the Elcometer 108; one is fitted with a dial pressure gauge and the other is fitted
with a digital pressure gauge.
The tester is a reliable and simple gauge which measures the pressure required to push an area of coating
away from the substrate.
The surface under examination is prepared and then a test dolly is attached by adhesive. A pin on the tester
fits into the centre of the dolly. The operator turns the instrument handle to increase the hydraulic pressure
on the pin. The pin is forced into the substrate and pushes the dolly away from the coated surface. When
the stress exceeds the adhesion of the coating, the dolly and coating detach from the substrate. The
