ABSTRACT:
A method and apparatus for the colorimetric testing of non-opaque fluids that comprises compact test kit apparatus made from readily available plastic components, and sets of such test kits made even more compact by a combination of chemistries for certain tests that simplifies and improves the accuracy of those tests while reducing the number of test kits required in a set. The colorimeter component of each test kit provides non-opaque colored plastic windows made from readily available commercial materials that are accurately color controlled. The colorimeter also makes automatic correction of the color windows to compensate for any initial coloration in the fluid being tested. The colorimeter also serves as the container for one complete kit and allows a set of kits to hang from closely spaced hooks to conserve space and make them exceptionally convenient to use. The use of readily available commercial components and materials avoids the expense of special tooling but more particularly eliminates the high costs usually associated with the very accurate color control needed by good colorimeters. The kit also has reagent containers that can be closed at negative pressure and hermetically sealed until the user converts them into dropper vials. Structurally the kit comprises tubular reagent container vials that nest with tubular sampler vials that nest with the tubular colorimeter with its non-opaque color patch windows.
