MiniAir20
Vane probes:
46
As the probes are highly sensitive measuring
instruments, they must be cleaned with very great
care.
Fibres or other foreign bodies can be carefully
removed with fine tweezers.
When doing so, take care not to bend or otherwise
damage the vanes or the spindle.
The adjustment of the bearing screws must
never be changed. This can result in erroneous
measurements.
Never allow hard objects to contact rotating
impellers!!!
Cleaning agents which extract the plasticizer from
the plastic are never to be used for plastic probes
(practically all solvents!).
We recommend the following for cleaning the
probes:
- running water
- soapy water
- pure benzene
Cleaning example:
1) Carefully swish the top part of the impeller back
and forth in clean, pure benzene for ca. 10 min.
Then swish the top part of the impeller back and
forth in clean kerosene for ca. 1 min. to re-
lubricate the impeller bearings.
If soapy water is used as a cleaning agent it is
advisable to wash out the soap solution thoroughly
with distilled water before lubrication with kerosene.
2) After cleaning the probe, rub it dry externally with
a clean, dry, fluff-free cloth.
3) Leave the top part of the impeller to dry for ca. 30
minutes.
