Thin film probes have been used for more than a decade to investigate turbulence, mostly in liquids. Many improvements have been achieved in the technique. Some problems still remain, however, so that the use of hot-film anemometers is not as straightforward as would be expected at a time when numerous ready-to-use probes and associated electronic equipment are commercially available. The following points should be discussed: aerodynamic perturbation caused by the probes, direct experimental check of the frequency response of constant temperature anemometers in the case of small fluctuations, dynamic non-linear behavior of constant temperature anemometers and heat transfer from hot films to their glass substrate.
