Exceptional Process pH Sensor Performance with the Differential Electrode pHD Measurement Technique  差分電極pHD測量技術展現優異的線上pH感測器效能
This field-proven technique uses three electrodes instead of the two normally used in conventional pH sensors. Process and reference electrodes measure the pH differentially with respect to a third ground electrode. The end result is unsurpassed measurement accuracy, reduced reference junction potential, and elimination of sensor ground loops. These process pH sensors provide greater reliability, resulting in less downtime and maintenance.  此經過現場驗證的技術採用三個電極，而非傳統pH感測器常使用的兩個電極。Process電極和 Reference電極透過與第三個接地電極進行差分測量來測量pH值。展現優異的測量精準度、更低的參考電極結電位，並消除感測器接地迴路。此pH感測器具有更高的可靠度，因而減少停機時間和維護需求。
