Knick - Model SE 554 -Low-Maintenance pH Sensor

• Low maintenance, no refilling of electrolyte
• Integrated sensor diagnostics
• Open junctions, no blocking
• Alpha glass, medium impedance, universal glass, fluoride resistant

• Perfect galvanic isolation thanks to Memosens technology
• No influence of humidity in the connector
• Digital data transfer
• Precalibration in the lab
• Integrated sensor diagnostics
• Simultaneous measurement of pH and ORP

High accuracy, stability, rapidness, and a long life cycle are achieved by the special design. Through 2 open junctions, the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction. The high content and special distribution of potassium chloride in the polymer reduces measurement disturbances which could be caused by liquid junction potentials.

Measurement in media of extremely high ionic strength, salt brines, strongly oxidizing media, acidic and alkaline media, Industrial applications, dyes, precipitation reactions, polluted media
