7.7 Temperature, humidity and air speed sensor (model 1154)
This sensor also has an integrated anemometer for air speed. The compact design of the sensor was
optimised for use in combination with the isokinetic duct probe and the direct determination of the air
speed in air ducts. Another application is monitoring the air speed in a preferred direction during a parti-
cle measurement, e.g. for source studies or ventilation testing.
