โฆ Synopsis
Commercially available anemometers generally are used at air velocities above the c m / s range. The present contribution deals with a micro-anemometer developed for measuring air velocities in the c m / s range. For the calibration at these low velocities a calibration unit has been built which creates air velocities in this range with an accuracy of the order of one percent.

A rig for the calibration of hot-wire anemometer probes at velocities below 1 m/s that uses a stepping motor to drive the probe at controlled velocities down the center of an enclosed channel is described. A typical calibration curve (over the range 0.02-1 m/s) displays the usual characteristics of
