AIR SPEED MEASUREMENT INCL. CO
2
-MEASUREMENT | WÖHLER FA 430
ADVANTAGES
· Two measurements in one step: de-
termination of flow rate and evaluation
of the inlet and exhaust air quality via
CO
2
, T, RH
· Easy handling with automatic identifi-
cation of the cone
· Measurement report via IR-transfer
to the Wöhler TD 100 Thermal Fast
Printer
· Wöhler Telescope Handle e.g. for
ceiling vents
· Selectable units: m/s, fpm, m³/h,
CFM, °C, °F, cm², Inch², ppm, %, RH,
WBT, DP
· Determination of the dew point and
wet bulb temperature
· Hold-Function
· Min- / Max-Function
· Backlight LC display
· Simultaneous measurement of wet
bulb temperature and dew point
APPLICATION
· Measurement of air velocity, tempera-
ture, humidity, CO
2
at the air vents
· Integrated measurement of flow rate
· Direct measurement of flow rate at the
air nozzle in combination with a funnel
· Determination of the
inlet and exhaust air quality
