Knick – SE 554 Memosens pH & ORP Sensor


Low-maintenance sensor for demanding process applications in the chemical industry, digital, with Memosens technology. The special design provides high accuracy, stability, speed, and a long life cycle. 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.

Available in 120mm & 225mm lengths with a standard PG13.5 connection
