pH/ORP Sensors PH8EFP, PH8ERP, OR8EFG, OR8ERG

Yokogawa's pH and ORP analyzers are highly reliable. They feature advanced functions and are useful for a wide variety of applications including water quality management in a broad range of production processes and in medium-sized wastewater treatment plants, or as general pH and ORP control systems.

Based on Yokogawa's track record and years of experience, a comprehensive range of products has been produced to provide solutions best suited to individual applications.

In addition to the PH8EFP, PH8ERP, OR8EFG and OR8ERG standard Ryton pH and ORP sensors, specialty pH and ORP sensors are available for various applications.

Although pH / ORP sensor was used as an analog detector in the past, it became possible to use it as a digital detector (with Variopin connector) by installing the SENCOM Smart Adapter SA11. pH / ORP sensor is a pH detector that compatible to on-site use and various combinations.

Ryton pH/ORP sensors PH8EFP, PH8ERP, OR8EFG, OR8ERG

  • With a body made of Ryton, a strong engineering plastic which is comparable to Teflon in terms of corrosion resistance and heat resistance, a wide range of applications are possible.
  • A single type of electrode can support all applications regardless of whether a holder or cleaner is used.
  • The integrated-electrode design simplifies calibration with standard solutions and maintenance.
  • The glass electrode of a pH analyzer, the platinum or gold electrode, and the junction of an ORP analyzer can each be easily replaced.
  • By combining pH and ORP sensor with SENCOM Smart Adapter SA 11, it becomes a digital detector. Yokogawa provides open environment with higher model.

Przegląd:

Cyanide-bearing wastewater from mining and electroplating facilities and certain types of chemical plants is toxic and must be treated by oxidation with chlorine or chloride to bring the cyanide concentration within regulatory limits.

Industry:Electrical and Electronics

Przegląd:

In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.

Industry:Chemical, Power

Przegląd:

The lifetime of a pH sensor has a significant impact on the overall annual costs of a pH measuring loop. Optimizing four key factors will decrease these costs and optimize process control and overall plant efficiency.
