All-in-One pH/ORP Harsh Applications FU24

The FU24 is an all-on-one pH and ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications.  It is particularly useful in applications with fluctuating pressure and/or temperature. These processes shorten sensor life because the process fluids move in and out of the sensor under influence of frequent pressure and/or temperature fluctuations. This results in fast desalting and dilution of the reference electrolyte which in turn changes the reference voltage causing a drifting pH measurement.

By integrating the successful Yokogawa patented Bellow design concept within the FU24 electrode, a strong pressure compensation mechanism is created. The built-in bellow ensures immediate interior pressure equalization to the outside pressure, making the sensor virtually insensitive to external pressure variations. A slight overpressure caused by the bellow tension, prevents fluid ingress and maintains a positive ion flow out of the sensor.

• Saturated Ag/AgCl reference system with double junction combined with polymerized saturated KCl and ion-trap prolong the life of the reference probe even in chemically unfavorable environments.

• Porous PTFE reference diaphragm to prevent fouling and reduce measurement error.

• Integral Pt1000 element for accurate temperature measurements and enhanced pH accuracy

• Solid Platinum ORP/LE electrode for accurate simultaneous pH and ORP measurements.

• Versatile in-line, immersion or off-line installation.

• Polymerized electrolyte to extend the sensors life time.

• Variopin connector

• Available in two versions, a robust dome shape model for applications with a limited amount of solids, and a flat surface model for applications in which solids are a considerable component
