(Deutsch) Glass-Lined Probes

For highest process standards

Conductivity probe type LF

The LF sensor type accurately measures the conductivity value in harsh applications. 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 LF probes are available in a rod design (with different lengths) and a ring design.
