|
|
|
· +/-2%
Production Tolerance
|
|
· Close production
tolerance permits replacement and interchange of orifices without loss of
acceptable accuracy.
|
|
· Save a
considerable sum. Purchase only one cup with all six orifices instead of six
complete cups.
|
|
· New
precision Snap-In Snap-Out orifices make it easy to change cup orifice
size.
|
|
· All Gardco Ford cups are alodine
finished machined aluminum with removable brass orifice.
|
|
· Six
orifice sizes: No. 0, 1, 2, 3, 4, 5.
|
|
· Series
range extends from 2 to 1413 centistokes.
|
|
· New
seconds to centistokes conversion table furnished with every cup.
|
|
· Calibration
traceable to the U.S. National Institute of Standards and Technology.
|
|
· Qualifies
under ANSI/NCSL Z540-1 or ISO/IEC 17025:2005, ISO 9001:2008 as applicable.
Conforms to ISO 9000 when ordered with calibration certification.
|
· Cup No. 5
compatible to requirements of Federal specification MMM-A-121 for Adhesives.
|
|
|
|
Additional Features
|
|
· The flow formula for each cup
in the series has been selected to provide results which are as close as
possible to an
|
|
average
of other similar Ford Cups.
|
|
·
The flow formula as applied to the
physical dimensions of each cup in the series has been confirmed with the use
of
|
|
standard oils
traceable to National Institute of Standards and Technology and other liquids
from essentially zero viscosity
|
|
to a viscosity
proportional to 150 seconds flow time.
|
|
·
Cup dimensions influencing flow time conform to
those specified in ASTM D-1200 except for very minor adjustment of
|
|
orifice
diameter.
|
|
· Weight of the cup
has been reduced by 20% to minimize influence of cup temperature on the
temperature of the
|
|
material
being measured.
|
|
· The top interior of the orifice
has been shaped to provide a sharper break in the stream as the cup empties.
This design
|
|
also provides
for a better definable orifice length with respect to theory.
|
|
· The taper fit of the
orifice eliminates hard to clean areas.
|
|
· The orifice is readily
removable with furnished wood dowel and inserted without the use of tools.
|
|
· The design of the
bottom of the cup gives increased protection to the orifice.
|
|
· The drip ring has been deepened
to accommodate a greater amount of material.
|
|
· A specially designed
tripod support is available to enhance the use of the cup.

Care of Cup
|
|
The
GARDCO viscosity cups are precision instruments. To maintain them in their
initial condition and calibration, they should
|
|
be cleaned
following each use with a suitable solvent and a soft brush or lint-free
cloth, Particular care should be used in
|
|
cleaning the orifice to avoid leaving
deposits or scratches on the internal surfaces. Nylon fishing line has been
found to be
|
|
suitable. It is good practice to retain
a pint of standard calibration oil which can be used to periodically insure
that the
|
|
cup maintains initial calibration.
