During operation of a fixing bath it is necessary to check the silver content as well as the pH in regular intervals to insure proper operation. A decrease in fixing capacity is noted as an increase in silver concentration of an alteration of the pH value. The convenient Ag-Fix test sticks allow a simultaneous semi-quantitative determination of silver and the pH value in photographic solutions. With these sticks two paper zones are sealed onto the lower end of a plastic strip, one for the determination of the silver concentration and one for pH measurement. Silver (gradations): 0.5, 1, 2, 3, 5, 7, 10 g/L Ag+ pH 4, 5, 6, 7, 8 Instruction Sheet
