Digital Combined pH/ORP Sensor

E+H/Endress+Hauser

• Chemical processes and process monitoring • Rapid fluctuations in pH or ORP values • Highly concentrated toxic media, e.g. H₂S • Approved for use in Ex Zones 0, 1 and 2 with ATEX, IECEx, CSA C/US, NEPSI, JPN and INMETRO certifications. • Memosens 2.0 supports an extended memory unit to store calibration and process parameters for improved trend recognition, providing an ideal foundation for future predictive maintenance and enhanced IIoT services. • Simultaneous measurement of pH, ORP and rH values (in rH mode) delivers comprehensive process information as a solid basis for stringent process control. • Optional pressurised reference system for reliable measurement of clog‑prone media such as dispersions. • Specialised ion trap on the electrode effectively prevents toxic diffusion into the lead and reference system, ensuring long service life. • Electrode can be mounted upside‑down for flexible installation. • Non‑contact inductive signal transmission ensures high process safety. • Minimised production downtime, extended electrode service life and reduced operating costs.
