The sensor S7P1 is used for digital measurement of pH in pure water, wastewater treatment plants, suspended solid fouling processes, coagulation and flocculation, scrubbers, etc. The new cast-in-place solid reference electrolyte helps maintain a constant reference cell potential by resisting dilution over time with pressure and temperature changes. The new capillary temperature sensor design places the PT100 behind the pH-sensitive membrane to guarantee more accurate temperature compensation and measurement.
