SE515 pH Sensor | Memosens | 120 mm | Sigma glass | For water and wastewater treatment

Description

SE515 pH Sensor | Memosens | 120 mm | Sigma glass | For water and wastewater treatment

Reasonably priced sensor for water and wastewater treatment

  • Perfect galvanic isolation thanks to Memosens technology
  • No influence of humidity in the connector 
  • Precalibration in the lab
  • Digital data transfer
  • Integrated sensor diagnostics
  • Low maintenance, no refilling of electrolyte
  • Integrated temperature detector 
  • Ground-glass sleeve junction
  • Sigma glass; low impedance for low-temperature applications

Thanks to its ground-glass sleeve junction even applicable in heavily contaminated media. Designed for MemoRail applications. High stability and a long life cycle are achieved by the special design.  

Through a ground-glass sleeve junction the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction. 

Measurement is possible even at low temperatures thanks to a special low-impedance glass. 

We look forward to hearing from you!
