Abstract : An air tunnel device is provided for use in combination with a thermohygrometer of the type where the change of resistance of the probe in response to changes in the ambient atmosphere is used to measure the temperature and humidity of the atmosphere. The device includes a housing which defines an air passageway therethrough, a probe support for mounting the probe of the thermohygrometer so that the probe is exposed to the air passagement in the housing and a fan mounted in the housing below the probe support for drawing air into the air passageway and thus providing air flow at a constant velocity past the probe.
