ABSTRACT An improved test means, device and method for determining the ionic strength or specific gravity of an aqueous sample are disclosed. The test means comprises a weakly basic polyelectrolyte polymer salt and an indicator means capable of producing a detect- able response to ion exchange between the polymer salt and the test sample. The polymer salt is one in which one or more of the basic moieties of the polymer is present as the salt of a strong organic acid.
