1.1 Important information
!
Carefully study and observe all items of these operating instruc-
tions before commissioning the unit.
!
In principle, the Ventilation Instrument SWF 233 should only be
used by skilled personnel for its intended purpose and within the
specified range of data. Any liability or warranty for results esta-
blished or for defects caused when using the unit is excluded by
all means.
1.2 Application
The Ventilation Instrument SWF 233 is ideal for the examination of the ex-
haust air and supply air openings at air conditioning systems.
The funnel of the SWA 233 is covered by a thermal hot wire sensor. The
measured airflow influences the sensor resistance. The current needed to
stabilize the hot wire temperature is proportional to the air flow. This principle
allows quick response time, precise measurement and indicates variations
in the air flow. Due to the very low aerodynamic resistance of the SWA 233
(typ. 0.01" water column at 2700 ft
measurement itself.
The measuring equipment includes:
- Flow capture instrument for exhaust flows up to 190 x 200 mm
- Telescopic handle
- Carrying case
- Battery charger
