PURPOSE:To make quick the overall judgement, by enabling to conduct the measurement of the degree of coloring of filter and that of clogging speed totally almost at the same time, through the provision of the filtering test and colormetric test sections closely and conducting of both the tests continuously. CONSTITUTION:A membrane filter 2 is supplied from a roll 1 and fed to a filtering test section 4 via a guide roll 3. A colormetric test section 9 is provided adjacent to the section 4. After the end of filtering test at the section 4, the filter 2 is fed for a given amount with the roll 13 to move a floating material catch section 12 on a reflecting mirror 10 of the section 9 for colormetric test. Further, in the filtering test, a filter 2 is press-contacted between upper and lower filter discs 4b, 4a with the operation of a cylinder 8, and the water to be tested from a water supply tube 7a is filtered to a drain tube 7b via the filter 2. Further, in the colormetric test, the reflecting mirror 10 is operated to picture the catched material 12, and color tone and degree of color are determined with the contrast with the standard color plate 11. |
