Knick - Model SE 557 -pH Sensor

• High accuracy
• Extensive measuring range for pH and temperature
• Refillable liquid electrolyte
• 2 ceramic junctions
• Self cleaning due to pressurization
• Integrated temperature detector
• Alpha glass, medium impedance, universal glass, fluoride resistant

• Perfect galvanic isolation thanks to Memosens technology
• No influence of humidity in the connector
• Precalibration in the lab
• Digital data transfer
• Integrated sensor diagnostics
• Omega glass, high impedance for high-temperature applications, very low alkali error, CIP/SIP capable

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).

Boiler feed water, water for injection (WFI), semiconductor production, difficult process media requiring high measurement stability
