Why Your pH Reading Keeps Drifting: The Reference Electrode Problem Nobody Talks About
Every time a pH reading drifts, the glass bulb gets blamed. The operator recalibrates, the drift comes back within days, and eventually someone replaces the whole sensor. Nine times out of ten, the glass electrode was never the problem — a pattern we see repeatedly across process plants in Malaysia. The reference electrode is. Across […]
Hydrofluoric Acid and Standard pH Sensors: Why Glass Electrodes Fail and What to Use Instead
Put a standard glass pH electrode into a hydrofluoric acid stream and you are on a countdown. It might read fine for a few days. Then the slope drops, the response slows, and eventually the bulb itself starts to look etched or frosted. By the time someone pulls the sensor for inspection, the glass is […]
