In an earlier paper of this series, we showed that the dust concentration in the air flow ought to be assumed by the value of P^^・ which increased according to the dust piled upon the paper filter. And in the secondary paper, the collection efficiency of the paper filter and the specific resistance of the loaded dust were studied. And then, the recently a paper on the characteristics of the continuous measuring apparatus of the value of P^^・ has been presented. By the results of these investigations the continuous measuring apparatus of the dust concentration was manufactured for trial. The present report deals with the results of the measuring test of the dust concentration in the air using the trial apparatus. In spite of the fact that this measuring apparatus is simple in construction, measuring in a comparatively extensive area is possible provided it is properly handled. We have found out that the measuring of, for instance, the values of 0.004〜67.2g/m^3 is possible, which was used in the present experiment.
