<p>PURPOSE:To measure the moisture of a photosensitive material with high accuracy and with good reproducibility by reflecting a measured light which transmits a continuously running sample film to be received by an infrared moisture meter photo detecting portion. CONSTITUTION:Light from a light source 1 is applied to a continuously running sample film 4, and the measured light 6 which transmits the film 4 is reflected by a reflecting plate 2 comprising an anodic oxide film 32 provided on an aluminium plate 31. The reflected light 7 enters a photo detecting portion of an infrared moisture meter, and light reflected directly from the surface of the film 4 is not used, so that the moisture of a photo sensitive material including the moisture in the interior of a film, a film having low reflection factor and high transmission factor and a film, the surface of which is mirror-like and smooth can be measured with high accuracy and with good reproducibility.</p> |
