Product Description:
The Elcometer 126 and Elcometer 3240 are easy to use gauges and designed to measure the thickness of a coating.
Dry Film: The measurement of the difference in height between the surface of the coating and the bare surface of the substrate, given by 2 fixed resting points (or outer foot) and a central mobile sensor, indicates the thickness of the dry film.
Wet Film: A knurled screw is situated on the upper part of the gauge and enables the travel of the probe to be varied over a height of 500µm (20mils) until it touches the film. The difference between the resting points on the substrate and the probes indicates the film thickness.
How to use a Wet and Dry Gauge:
Wet Film Process:
Place the instrument on the coated substrate, the legs resting on the substrate, and simply take the measurement from substrate to the top of the wet film, measured by a knurled screw and displayed on the face of the gauge.

Dry Film Process:
Remove a small area of the coating to reveal the substrate and place the instrument above that area. The outer legs will rest on the coating surface and the central sensor is adjusted to touch the substrate. The coating thickness is displayed on the face of the gauge.
