Sensorex SD7000CD
5-Wire Differential Online Process pH Probe

SD7000 Series Differential pH Sensorr

Our SD7000 series differential pH sensor offers unsurpassed pH measurement accuracy by minimizing reference junction fouling and eliminating ground loops. These units deliver greater reliability and less required maintenance than a conventional combination pH sensor. Extended sensor lifetime can be achieved by replacing the sensor reference (salt bridge). Reliably measures pH in environments with rapid temperature changes with built-in quick response automatic temperature compensation (ATC).

  • Reliable measurement performance with true differential pH measurement technology using solution ground

  • Direct-fit compatibility for several popular Hach® & Water Analytics® models

  • Perfect for pressurized applications with sealed, no maintenance reference design
