ORP Sensors

Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control. Common measurements include pH, ORP, conductivity, resistivity, percent concentration and dissolved oxygen. Liquid analysis is essential for protecting capital assets including boilers and cooling towers, by preventing corrosion, minimizing maintenance, and maximizing uptime. Yokogawa is a recognized world leader for reliable liquid analytical equipment, providing accurate and repeatable solutions for maintaining and controlling even the most demanding process applications with unparalleled ease of operation.

Featured Solutions

  • FF20 FS20 Flow Fittings

    For liquid analysis, the sensors are usually mounted in either a flow or immersion fitting. As a result, we offer a full range of fittings with particular emphasis on designs that reduce installation and maintenance time and consequently save operation costs. A high degree of standardization makes it possible to mount electrodes with DIN dimensions directly into a fitting. For most other types a mounting kit is available.

  • FU20-PH20

    The PH20/FU20 all-in-one sensors feature four separate elements (pH, reference, temperature, ORP) allowing for the simultaneous measurement of pH and ORP. The FU20 features a rugged Ryton™ body and the PH20 features a PVDF body. The integral NPT threads on the sensors make installation convenient.

  • 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.

  • PH87/PH97 Retractable pH and ORP Assemblies and Electrodes

    The PH97 electrodes are designed to be durable and rugged for use with the PH87 assemblies. Each PH97 holds four separate elements in a rugged Ryton™ body which includes a pH bulb guard and an anti-blowout restraint. This pH system is composed of a metal impregnated Ryton™ solution ground, a double-junction reference, universal pH glass (0-14 pH) and a PT1000 temperature element.. In many applications the large volume reference reservoir will provide an extended functional life.

  • PR10

    The PR10 is a universal retractable assembly that is suitable for applications where the sensors must be removed without interrupting or shutting down the process. Without any special tools, it can be retracted safely from the process at pressures up to 5 bar (72 psi). The PR10 is designed to accept any commercially available pH/ORP or dissolved oxygen sensor that has a PG13.5 connection.
