Differential ORP Sensors

Differential ORP Sensors
ORP Sensors with Integrated Digital Electronics for Plug and Play Capability with Hach's Digital SC Controllers. Available in PEEK, Ryton, or Stainless Steel body materials and in multiple mounting styles.

The Sensors feature exceptional performance due to the Differential Electrode Measurement Technique. This field-proven technique uses three electrodes instead of the two normally used in conventional pH/ORP sensors. Process and reference electrodes measure the pH/ORP 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 sensors provide greater reliability, resulting in less downtime and maintenance.
