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

Designed for 2-wire (loop powered) system configuration. Standard mA (4-20), HART, Profibus, and Foundation Fieldbus communication available.

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).

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

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

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.

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.

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 PH87 assemblies. Each PH97 holds four separate elements in a rugged Ryton™ body which includes a pH bulb guard and an anti-blowout restraint.

Applications for the PR20 retractable fitting can be found in all processes where the pH sensor should be removed without interrupting its continuity (e.g. pulp slurries, pressurized systems).

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.

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.

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.

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.

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.
