(Deutsch) Glass-lined Probes

For highest process standards

pH/Redox probe type pH/ORP

The pH/ORP sensor type accurately measures pH and redox value in applications where conventional glass probes are unstable, drift and feature a short service life. The Pfaudler Heavy-Duty Design allows it to be installed in-line directly in the product flow. The wear-resistant, smooth glass-lined layer uses the product flow to keep the surface of the sensor clean while resisting any potential product build-up that may occur.

The pH/ORP probes are available in rod design (with different lengths) and also in ring design.
