Quantitiy Designation Explanation
A 1 Draft shield Protects the vessel (C) with the liquid to be weighed
from air drafts.
B 1 Evaporation
ring This ring is placed on the Weighing Cell (H) as shown
in the figure. It contains a groove that can be filled with
distilled or de-ionized water. During operation, part of
this liquid evaporates and thus increases the air
humidity under the draft shield. This, in turn, has the
effect that less liquid evaporates from the vessel dur-
ing the Gravimetric Test. In this way, the accuracy of
the test results is increased indirectly.
C 2 Vessel Contains the liquid to be weighed during the Gravimet-
ric Test. The vessel rests on the weighing pan (E).
D 1 Centering ring Holds the evaporation ring (B) in place
F 1 Adapter plate Plate with two handles and positioning slots that can
be placed in the appropriate grid position on the work-
table. It also has four positioning holes that allow posi-
tioning the Weighing Cell (H) properly on the plate.
G 4 Foot + counter-
nut The four feet are standard knurled screws with a plas-
tic head. They are screwed to the bottom of the Weigh-
ing Cell (H) and can be used to level out the Weighing
Cell. The counternuts serves for securing the feet.
