1 1. GENERAL 1-1. Introduction This instruction manual provides information for the installation and use of the FU20, four-in-one wide body pH sensors. The FU20 is the choice for the majority of typical waste water and process applications. The Model FU20 offers a simple and cost effective solution for a wide variety of waste water and process applications. This all-in-one sensor provides simultaneous measurement of pH, redox (ORP) and temperature if desired.

3 3. INSTALLATION OF FU20 For optimum measurement results, the FU20 should be installed in a location that offers an acceptable representation of the process composition and DOES NOT exceed the specifications of the sensor. The FU20 is designed with threads on either end of the body 3/4” NPT to allow installation in a wide variety of applications. 3-1. Typical Installation The FU20 sensor is designed for in-line installation, via a bypass loop as an immersion assembly.
