ABSTRACT:
A liquid testing kit for determining the pH value of a liquid body at various depths includes a pH tester and a liquid sampling container having a spring-hinged lid. The container is adapted to be lowered to various depths with the lid in open position. The hinge is then remotely triggered to close the lid at the desired depth whereupon the container is removed from the liquid body. A self-seating ridged planar seal is employed between the lid and the container. The removed container can be stood upright, and a plurality of vertical internal supporting webs are dimensioned so as to accommodate a pH test instrument in the container. The hinge includes a crank arm having a support post against which a closing or opening tensile force is applied. The crank arm is pivoted from a first position wherein the tensile force creates an opening moment to a position wherein the post lies on the opposite side of a pivot so that a tensile force at the same post creates a closing moment. A control line which is fixed to the crank arm remote from the pivot is employed for the purpose of lowering the sampling container to the desired level in the liquid and triggering the crank arm to close the lid.
