Filter the sampled water to see if there is no dust in the piping at the trial operation of the new construction work of the plant and check the state of the filter paper placed on it.

Even if you look at the product page, you do not know the size of the filter paper that conforms, even though it is wearing a "filter paper conforming type". It is unkind as a product introduction page. Since it is also a crocodile, it may be useless, but since the size of the funnel is made a little bigger, if the filter paper set deviates from the center, there may be a hole which is not blocked by the filter paper. I am glad that there is a material that can not be broken as a site use.
