This line of FLS electrodes has been designed to provide a cost effective solution for inline or submersible monitoring with a wide range of applications.

Single and double junction models are available, as well as models with or without a BNC connection on the electrode.

In addition, a pH option with integrated temperature sensor is available for the Automatic Temperature Compensation (ATC) function.

These epoxy resin body electrodes are suitable for many applications due to the high chemical resistance of the material.

For an economic line installation a simple reusable electrode holder can be used while the coupling with the ½” or ¾” extension allows submerged installation.

A special model is designed for installation on FLS T-adapters and FLS brackets with only the addition of a nut.
