ERWEKA RT 700
Detergents Tester RT 700 is versatile labora-
tory test equipment with which the washing
process of a common washing machine / dish-
washer can be simulated, in order to determine
different quality parameters of cleaning agents
(tabs).
The RT 700 is equipped with 7 test stations with
1.000 ml or 2.000 ml glass vessels and a fur-
ther station into which the supply of the immer-
sion cooler is integrated. The glass vessels are
integrated into a water bath, which can be
heated depending upon test requirements up to
45°C or cooled down to 10°C. The regulation of
the temperature takes place via the combina-
tion of a flow heater and a cooler. If the immer-
sion cooler is not needed, it can be removed.
Thereby an eighth test station becomes free.
Each of the 7 test stations allows paddles to
simulate the agitating movement of a washing
machine/dishwasher. The unit can be driven
with up to 300 min
-1
. The direction of rotation
can be changed after a freely adjustable break,
and thus the washing process is simulated op-
timally.
Using the adjustable test parameters of the RT
700 such as temperature, rate of motion and
duration of the test, most different test stan-
dards currently used by manufacturers of clean-
ing agents and dishwashers can be tested. In
each test the structure of the cleaning solution,
degree of water hardness, pH value, chloride,
etc., can be varied.
