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 Built for difficult applications & constructed of chemically-resistant Ryton Polyphenylene Sulfide (PPS) Two year limited warranty
