pH/ORP Meters
pH/ORP(redox) transmitters and their fitting and sensors
pH71/72 pH and/or ORP pocketmeter
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.
- PH450G 4-wire Transmitter
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.
- PH202G(S) 2-wire Transmitter
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.
- SC25V – Combined pH sensor with Liquid earth
The SC25V is the latest addition to the family. Yokogawa’s first combination pH sensor in a 12 mm design with an external Liquid earth. A new design made it possible to create a large electrolyte volume making this sensor last longer then most other comparable pH electrodes.
- SC24 differential pH sensor
The SC24 differential pH sensor is unique to the industry. Offering the possibility of maintenance free operation without any reference problems. In the SC24 differential pH sensor, the reference cell is made of glass, with no porous junction. No electrolyte is in contact with the process.
- PR10 Retractable Fitting
The new Yokogawa PR10 is a retractable sensor fitting that offers a flexible approach to online liquid analytical measurements in a wide range of process industries. Designed for online process applications where the sensor has to be removed safely without interrupting process continuity – in anaerobic, toxic or pressurised environments, for example, the PR10 is equally suited to pH, ORP, conductivity, inductive conductivity and dissolved oxygen measurements.
- SM21/SR20/SC21, SM29/SC29, SM60
Industrial 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.
- FU20 / PH20
pH/redox and temperature sensor
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.
- Hamilton Industrial Electrodes for pH/Redox
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.
- FF20/FS20 Flow Fittings
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.
- FD20 Immersion Fittings
For liquid analysis, the sensors are usually mounted in either a flow or an immersion fitting. Therefore Yokogawa has invested considarable 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.
- PR20 Retractable Fitting
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 series Compact pH Probes
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.
- FC20 Cleaning Systems
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.
- BA10/WF10 Connecting Equipment
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.
- Process Retractable fitting with Manual or Automatic Control unit
The retractable holder EXAtrac RF20 (Extrac 810 and 820) is made for installation of Ø12mm 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.
