Description

SE557 pH Sensor | Memosens | 120 mm | Ex | Alpha glass | For process media requiring high measurement stability

For special requirements and high-precision measurements with refillable liquid electrolyte, digital, with Memosens technology

  • Alpha glass, medium impedance, universal glass, fluoride resistant
  • High accuracy
  • Extensive measuring range for pH and temperature
  • Refillable liquid electrolyte
  • 2 ceramic junctions
  • Self cleaning due to pressurization
  • Integrated temperature detector
  • Perfect galvanic isolation thanks to Memosens technology
  • No influence of humidity in the connector
  • Precalibration in the lab
  • Digital data transfer
  • Integrated sensor diagnostics

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).

We look forward to hearing from you!
