三、pH 电极的选择和使用(续)(二)怎样正确使用 pH 电极工业废水处理流程中,pH 电极往往处于较恶劣的使用环境,pH 电极使用不当,不仅造成严重的测量误差,还会缩短电极的使用寿命,直接影响整个 pH 测量(或控制)系统的可靠性和稳定性。经验告诉我们,在测量(或控制)系统的设计阶段,从一开始就应充分考虑 pH 电极的使用条件。影响电间正常工作的有物理的和化学方面因素。物理的原因主要有:(1)生成的难溶物质或油污沾附在电极敏感膜
How to Correctly Use the pH Electrode In the process of industrial wastewater treatment, the pH electrode is often in a harsh environment. The improper use of the pH electrode not only causes serious measurement error but also shortens The lifetime of the electrode directly affects the reliability and stability of the entire pH measurement (or control) system. Experience has taught us that in the design phase of the measurement (or control) system, the pH electrode’s conditions of use should be fully taken into account from the outset. There are physical and chemical factors that affect the normal operation of the electricity. Physical reasons are: (1) the formation of insoluble substances or oil attached to the electrode sensitive membrane
