ORP Sensors

Oxidation Reduction Potential (ORP) electrodes and sensors are the sensing portions of a ORP measurement. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper ORP electrode/sensor selection is critical for optimal measurement results.

pH/ORP Calibration Solutions

MSDS are data sheets listing general chemical compositions and certain characteristics of chemicals.

Personal Handheld Meter PH71/PH72

The PH71/PH72 pH and/or ORP meter is a Compact, Easy-to-use, Drip proof – Ideal for Field Use. Features "One-Touch Calibration" and Temperature Compensation. Laboratory-Grade Intelligent pH Meters – Sized and Priced to Fit in Your Pocket

All-in-One pH/ORP Sensor Series FU20/FU24/PH20

The PH20, FU20 and FU24, all-in-one pH and ORP, sensors show how Yokogawa applies the motto "Simple is best" to sensor technology.

Differential pH/ORP Sensors

The cation differential pH and ORP sensors were designed for difficult applications where conventional sensors are ineffective. These include measurements such as brine solutions to applications as diverse as electrolysis processes and cheese manufacturing.

Industrial pH/ORP Electrodes

The heart of a pH measuring loop is the electrode system. Yokogawa has designed a wide range of electrodes to ensure this heart keeps beating under the most severe conditions.

Pure Water pH and ORP Sensors

Achieving accurate and reliable readings using a traditional pH analyzer is challenging, however with the right equipment stable and accurate pure water pH measurements can be accomplished. Yokogawa's specialized bellomatic pH sensor is proven best solution for high purity water applications. For those individuals that do not like the maintenance of refilling sensors, then the FU24 which incorporates the successful patented bellow system in an All-in-one body is the ideal solution.

pH and ORP Sensors PH4/OR4 Sensor Series

PH4/OR4 pH/ORP Sensor Series Allows pH/ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide.

 

Pharmaceutical pH and ORP Electrodes and Fittings

These sensors feature the latest innovations in pH glass formulation, reference systems, and reference electrolytes. They offer supperior accuracy and stability, even after repeated sterilizations.

Flow/NPT Fittings FF20/FS20

Yokogawa has invested considerable design and development time in producing a full range of fittings with particular emphasis on designs that reduce installation and maintenance time and consequently save operation costs.

Immersion Holder FD20

The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains. They have a "hoisting cable" for easy maintenance.

Hot-Tap Holder PR10

On-line measurements often present extra challenges, especially when routine maintenance is required. The PR10 is ideally suitable for applications where the sensors must be removed without interrupting or shutting down the process. Without any special tools the PR10 can be retracted safely from the process at pressures up to 5 bar (72 psi). Using the PR10 allows us to place any dissolved oxygen sensor that has a PG13.5 connenction into a retractable assembly.

pH/ORP Retractable PH87/PH97

The Model PH87 assemblies are constructed of chemically resistant titanium sheathes and are used with Model PH97 sensors. The retractable assembly is suitable for "Hot-Tap" service and is removable from a pressurized process line or vessel without interrupting the flow or draining the tank. The Model PH97 electrodes are designed to be durable and rugged for use with the PH87assemblies. Each PH97 holds four separate elements in a rugged Ryton™ body whichincludes a pH bulb guard and an anti-blowout restraint.

Pneumatic Retractables RF20H

The pneumatic retractable holder EXAtrac RF20 (Extrac 810 and 820) is made for installation of 12mm sensors on tanks or pipelines where the sensor has to be removed without interruptions or shutdowns and in the hash applications where frequent cleaning is of vital importance for a good pH measurement.

pH and ORP Applications with Coating Problems

A pH electrode is as good as its maintenance; this is especially true in harsh environments. For industrial applications and particularly for automatic process measurements it is of the greatest importance that the sensitive part of a glass electrode and the diaphragm of a reference electrode are kept clean.
