Method of measuring a silver or halogen ion concentration and an apparatus for the same |
摘要 |
<p>A method of measuring a silver or halogen ion concentration wherein, in a sensor system which detects as a potential a silver or halogen ion concentration in a gelatin aqueous solution containing silver halide crystals, a reference electrode which functions as a reference of a potential measurement is inserted into a heat insulating bath without being directly inserted into the measured liquid, said bath being accurately controlled to have a constant temperature and electrically insulated, the measured liquid and said reference electrode are electrically connected with each other by a salt bridge, only one end portion of an indicator electrode is immersed into the measured liquid, said reference electrode and another end portion of said indicator electrode are connected with a potentiometer, and a potential is measured. <IMAGE></p> |
