Abstract:
1. A liquid filter media sampler, comprising: a sample collecting section comprising a first outer tubular member and a first inner tubular member, said first inner tubular member rotatably carried within said first outer tubular member, each of said first outer and first inner tubular members having a first end and a second end and having an elongate opening parallel to a line extending from a point near said first end to a point near said second end, the inner tubular member defining a continuous media sample chamber having a length selected to collect a vertically continuous media sample through at least a transition zone of the filter media, a cap closing said first end of said first outer tubular member and rotatably supporting the inner tubular member, a coupler on the second end of each of said first inner and first outer tubular members, a first extension section comprising a second outer tubular member and a second inner tubular member, said second inner tubular member rotatably carried within said second outer tubular member, each of said second outer and second inner tubular members having a first end and a second end, a handle coupled to the second end of said second outer tubular member, a coupler on the first end of said second inner tubular member and adapted for releasable engagement with said coupler on the second end of said first inner tubular member, and a coupler on the first end of said second outer tubular member and adapted for releasable engagement with said coupler on the second end of said first outer tubular member, said coupler on the second end of said first outer tubular member and the coupler on the first end of said second outer tubular member comprising mating portions of a cam lever coupling adapted to couple said first outer tubular member to said second outer tubular member at any relative angular orientation to permit alignment of the handle attached to the second outer tubular member relative to the elongate opening of the first inner tubular member, and prevent relative rotation of said outer tubular members after coupling.
