Electrochemical measuring chain for measuring e.g. pH value of e.g. non-aqueous liquid used in battery, has indicator electrode and reference electrode for determination of hydrogen ions in measuring solution

摘要

The electrochemical measuring chain has two hydrogen electrodes and a galvanic cell (3) that are provided in a hydrogen source chamber (2) to form a rod-like structural unit. The hydrogen electrodes such as indicator electrode (8) and reference electrode (9) are provided for determination of hydrogen ions in measuring solution. The reference electrode is arranged around the indicator electrode. The hydrogen electrodes are formed of platinum, palladium, and PTFE. A pressure sensor is provided for measuring the pressure of hydrogen gas.
