GENERAL-PURPOSE INTEGRAL ION-SELECTION TRANSDUCER

FIELD: instruments for measuring ion content and testing waste drain. SUBSTANCE: device has hollow housing with insertion which is shaped as inner surface of housing and has two through channels which are parallel to one another and are designed for removable solid-state electrolyte indicator electrode and removable comparison electrode with electrolyte which has thickening agent of acrylamide and N,N"-methylene acrylamide. In addition transducer may have hollow housing which is filled with electrolyte and contains comparison electrode with inner electrolyte and removable solid-state electrolyte electrode. Housing electrolyte and comparison electrode electrolyte have same thickening agent. Content of thickening agent in housing electrolyte is greater than that in inner electrolyte of comparison electrode. EFFECT: increased functional capabilities. 5 cl, 10 dwg, 3 tblf
