<p>The present invention relates to an opening and closing type sampler for well water, which can collect and analyze accurate data on a sample. The inserting type sampler comprises: a tube-shaped main body which includes an internal space at a fixed size in order to collect a sample from a monitoring well, and includes a penetration type opening hole which is a path for an inflow of the sample into the internal space or the outflow of the sample to the outside; an opening and closing cover rotatably placed on one side of an edge unit of the opening hole in order to selectively open or close the opening hole formed on the main body; and a rotary driving unit which selectively opens or closes the opening hole by rotating the opening and closing cover. Therefore, the opening and closing type sampler for well water can collect and analyze accurate data on a sample by preventing the inflow of foreign materials into the sample during the discharge of the sample collected from a monitoring well to the outside of a collector in order to prevent cross contamination of the sample.</p> |
