More details from Sensorex:
The SD7000CD and SD7000CD-ORP pH & ORP sensors are a reliable, low maintenance solution for online process control. By employing differential sensor technology, these products offer advantages over conventional combination sensors. The differential design employs two glass electrodes, which record pH or ORP measurements differentially with respect to a third metal electrode. Using a second glass electrode to create a standard reference cell permits the use of a known buffer solution, which resists pH change. Consequently, the reference cell is less susceptible to contamination, which might otherwise lead to additional maintenance and downtime. This technique also provides unsurpassed accuracy by virtually eliminating ground loops.
In environments with rapid temperature changes, the SD7000 series ensures measurement accuracy through built-in quick response automatic temperature compensation (ATC). Extended sensor lifetime can be achieved by replacing the sensor reference (salt bridge), a feature that is impossible for conventional combination models. The benefits of differential sensor technology make the SD7000 series an excellent solution for difficult applications, including high temperature and high pressure process control.
