Wet Film Thickness Gauge, Model 234
|
|
in accordance with ISO 2808, ASTM
D1212, BS 3900: C5
|
|
Reference Class
|
|
|
|
The
physical and mechanical properties of a coating are directly dependent on the
film thickness.
|
|
If
meaningful testing is to be conducted, the film thickness must therefore be
uniform.
|
|
|
|
Wet
film thickness gauges are used to check freshly applied coatings
and can also be used to calculate
|
|
the resulting
dry film thickness. If deviations from the specified value are detected,
corrective measures
|
|
can be taken
immediately.
|
|
|
|
Dry
film thickness gauges are used to check finished coatings.
|
|
|
|
Mechanical
film thickness gauges provide a number of advantages:
|
|
§ Handy,
portable, and simple to operate, even by unskilled personnel. Sturdy
construction, direct reading.
|
|
§ Measurements
can be carried out on any surface. Since the system functions completely
mechanically, substrates of glass, wood, metal or plastic are permissible.
|
|
§ In
comparison to other systems, mechanical film thickness gauges are favourably priced.

Reference
Class:
|
|
All
versions of Model 234 R are supplied with a Manufacturers Certificate M
in accordance with DIN 55 350-18
|
|
that
includes among others the following information:
|
|
|
|
Setting
and actual values for the gap heights related to the scale values, product identification,
test equipments
|
|
used with
calibration status, date, name of inspector.
|
|
|
|
The
gap heights are measured by means of a digital dial gauge at 6 spots evenly
spread over the measuring area
|
|
and compared
with the setting values read on the scale.
|
|
|
|
Application
|
|
On
all flat or uniformly curved (concave and convex) surfaces.
|
|
|
|
Design
and Function
|
|
The
hardened, precision-ground measuring disc of stainless steel is 50 mm in
diameter and 11 mm thick. It features a
|
|
freely rotating aluminium guide roller to enable the instrument to be
rolled over the surface.
|
|
|
|
Available
in 8 different versions and measurement ranges (see order information).
|
|
|
|
The
read-out scale is engraved on one side around the periphery of the disc. Each
instrument is supplied in a case.
