ALTANA Inmont-Gages - Manual (Page 3)

Description
A precision instrument used for accurately
measuring the wet fi lm thickness of paint, ink,
adhesives or other wet fi lm on a static or moving
surface, in the lab, in the fi eld or on the production
line.
Model S:
The gage is precision machined from a single
piece of stainless steel for structural integrity
and corrosion resistance. It consists of a smaller,
eccentric inner wheel supported by two concentric
outer wheels so as to provide two scales that
are bilaterally symmetrical. A scale in mils
(thousandths of an inch) or microns is etched
into the outside surface corresponding with the
range of the gage. The range is determined by
the minimum and maximum clearances between
the reference plane, defi ned by the diameter of
the two outside wheels, and the diameter of the
eccentric. As the gage is rolled over the sample,
the clearance between the inner wheel and the
plane defi ned by the outer wheels varies. The
point at which the inner wheel fi rst contacts the
wet fi lm is the thickness of the coating.
Model R:
This version is quality made exactly as above with
the addition of a rotating scale which includes a
pointerm bent around the wheel of the gage, to
facilitate locating the end of the coating pickup
point on the eccentric in reference to the scale
reading. This scale/pointer is designed to eliminate
parallax and therefore increase the accuracy and
precision of the reading.
