ABSTRACT:
A device for determining the levels of a predetermined substance in a predetermined volume of a fluid has an inner tube, a mass in the inner tube of a material that changes properties when exposed to the substance so that when the fluid passes through the mass the substance changes, an outer protective tube surrounding the inner tube and having an open end, a frangible seal sheet covering the open outer-tube end, and a test element having an end pierceable through the sheet and fittable with an end of the inner tube. Thus to install the cartridge formed by the inner tube and its contents on the test element, same is merely poked through the seal to simultaneously open the package and fit over the inner tube.
