SE 551 Memosens® pH Sensor

For special requirements and ultraprecise 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. Two ceramic junctions, self cleaning due to pressurization (continuous outflow of electrolyte). Silver ion trap prevents junction fouling and contamination.

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

Facts
– perfect galvanic isolation thanks to Memosens® technology
– no influence of humidity in the connector
– precalibration in the lab
– digital data transfer
– integrated sensor diagnostics
– high accuracy
– extensive temperature range for pH and temperature
– refillable liquid electrolyte
– two ceramic junctions
– self cleaning due to pressurization
– silver ion trap
– integrated temperature detector
– CIP and SIP capable
