Product Specification

SE 557 Memosens pH Sensor
For special requirements and high-precision measurements with refillable liquid electrolyte, digital, with Memosens technology

Elimination of typical junction problems resulting in high measurement accuracy in ultrapure water as well as in heavily polluted media and at high temperatures. Integrated, refillable liquid electrolyte reservoir. 2 ceramic junctions, self cleaning due to pressurization (continuous outflow of electrolyte). Silver ion trap prevents junction fouling and contamination.

SE 557 Memosens pH Sensor Applications
Boiler feed water, water for injection (WFI), semiconductor production, media containing proteins or sulfides, difficult process media requiring high measurement stability
