Compact, Easy-to-Use, and Drip-proof, the PH72 is designed specifically to meet the needs of both the field and the laboratory. This portable pH meter includes advanced features such as optional ORP measurement (with appropriate electrodes), Automatic or Manual Temperature Compensation, and several calibration options.

The EXAxt 450 series is designed to combine the superior functionality of the Yokogawa EXA series with the ease of use offered in pocket computers (PDA). The PH450 offers the best accuracy in the industry by combining the pH measurement with advanced temperature compensation functionality, preloaded calibration standards and stability checks.

Fieldbusses are based on highly reliable bi-directional communications between “smart” field devices and HOST systems. Next to a wide range of data each smart device can provide their status which is essential for adequate control and maintenance. The famous EXA sensor diagnostics will provide asset management facilities for those who operate and maintain the plant.

The EXA100 series is a simple, reliable panel-mountable pH Analyzer providing all the basic functionalities required for water treatment applications. It is ideal for cost-sensitive unattended applications where panel space is important.

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.

The PH20 is nicknamed "Tempress" because of the patented compensation for changes in the process temperature and pressure. This simple mechanical feature makes the sensor more accurate, and gives it a longer lifetime. The FU20 combination sensors show how Yokogawa applies the motto "Simply the Best" to sensor technology. The wide body sensors (26 mm diameter) hold four separate elements in one unbreakable PPS 40GF (RytonTM) body.

When you purchase an analyzer system from Yokogawa, you know you are getting the ultimate technology fit for your purpose. Because Yokogawa is a global leader in analyzer technology based on an outstanding track record of continuous innovation. And now Yokogawa has signed a Global Preferred Vendor Agreement with the Hamilton Company a world leader in sensor technology.

For liquid analysis, the sensors are usually mounted in either a flow or an immersion fitting. Therefore 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.

With pH measurements in chemical processes, a combined pH/ reference electrode is usually mounted in a by-pass flow fitting, a flanged immersion fitting or an on-line retractable fitting.

EXA Compact is available as a flow type, an insertion type and an immersion type of fitting. A wide choice of process connections is available to make installation in a tank, open basin or pipe/bypass very simple. The careful choice of chemically resistant materials makes it suitable for most processes.

Often it is not practical to interrupt a process for cleaning the electrodes, an accurate indication is required over a long period, replacing the electrodes is difficult, etc. Then an automatic cleaning mechanism may be the solution.

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.
