Smell gas flow visualization device and smell gas flow measuring device

摘要

PROBLEM TO BE SOLVED: To provide an odor/gas flow visualizing device used without requiring selection of a gas sensor arrangement position and hardly affected by a local turbulence of wind so as to quickly determine the direction of the odor/gas flow with high reliability. ;SOLUTION: This device is provided with an odor/gas flow measurement means consisting of a combination of a plurality of sensor arrays, in each of which a single or more odor/gas sensor is arranged on a two-dimensional plane, and measuring a change of concentration of odor/gas flow in multiple points and a visualizing means visualizing the concentration change measured by the odor/gas flow measuring means.;COPYRIGHT: (C)2001,JPO
