German Knick SE 554 Memosens pH sensor
The pH sensor SE 554 is a low-maintenance sensor suitable for demanding processing applications in the chemical industry. Digital. High precision, high stability, high speed, and long operating life are achieved through special design. The reference system is in direct contact with the measured medium through two open junctions. The junction has almost no risk of contamination or blockage. The high and specially distributed potassium chloride content in the polymer reduces measurement disturbances that may be caused by liquid junction potentials.
