Product Group Information

PH72 Personal pH/ORP Meter
The PH72 pH meter is 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

EXA PH202 2-Wire pH / ORP Analyzer
Designed for 2-wire (loop powered) system configuration. Standard mA (4-20), HART, Profibus, and Foundation Fieldbus communication available.

EXAxt PH450 4-Wire Analyzer for pH / ORP
The new EXAxt 450 series builds on the superior functionality of the industry leading Yokogawa EXA series by enhancing the EXA’s proven operation and application flexibility. The Model 450 series feature a uniquely simple touch screen menu structure that offers a choice of five different languages (English, French, German, Italian or Spanish).

FU20 & PH20 pH/ORP Combination Sensor
The PH20 and FU20 all-in-one sensors show how Yokogawa applies the motto “Simple is best” to sensor technology.

SC24V 12mm 4-in-One Differential pH Sensor

The SC24V differential pH sensor is unique to the industry, offering maintenance free operation without any reference problems. In the SC24V differential pH sensor, the reference cell is made of glass, with no porous junction, so no electrolyte is in contact with the process.

PH18 Differential pH Sensor
The model PH18 differential pH sensor is unique and offers the possibility of maintenance free operation for the correct application.

Separate pH and ORP Electrodes for Industrial Applications
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.

Pharmaceutical pH 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.

PH87/PH97 Retractable "Hot-Tap" pH Assemblies and Electrodes
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.

PR10 Retractable "Hot-Tap" Fitting

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).

FF20/FS20 Flow Fittings and NPT Adapters
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.

FD20 Immersion Fitting
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.

BA10 Junction Box/ WF10 Cables
Between measuring plant and control room, especially when the distance between these places is greater than the length of the standard appropriate electrode cables, the connecting equipment can be an expedient method for connecting sensor cables to a measuring instrument.

Cleaning System
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.

PC Flow Block for Biotech and Pharmaceutical Applications
Many botech and pharmaceutical applications for determining the purity and quality of the finished product, require the measurement of pH and conductivity in very low volume samples. The PC Flow Block assemblies were specifically designed to achieve accurate pH and conductivity measurements in such low volume applications.
