Electrode Extravaganza: pH Electrodes Measure Up to Their Potential

So what has changed? "Electrodes themselves are pretty much unchanged," remarks Peter Hail of Hanna Instruments. "What have changed are the applications and systems; the instruments behind them have changed." While makers of electrodes still optimize and fine-tune pH electrodes, in general, the design of the electrodes and their methods of measurement have remained relatively stable. Hail contends the meters backing the electrodes are becoming more integrated and smaller. After taking a look at what's on the market, it becomes obvious that, indeed, although hundreds of ...
