Sensorex SD7000CD-ORP 5-Wire
Differential Online Process ORP Sensor

Sensorex SD7000CD-ORP 5-Wire Differential Online Process ORP Sensor

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

  • Reliable measurement performance: True differential ORP measurement technology using solution ground

  • Direct-fit Compatibility: Replacement sensor for several popular Hach® & Water Analytics® models

  • Perfect for pressurized applications: Sealed, no maintenance reference design

  • Built for difficult applications: Constructed of chemically-resistant Ryton Polyphenylene Sulfide (PPS)

  • Two year limited warranty: We stand behind all our products with the Sensorex Guarantee
