Description

SE558 pH Sensor | Memosens | 225 mm | Ex | For ultrapure water, water and analytical chemistry

For uncomplicated measurement in ultrapure water, water and analytical chemistry, digital, with Memosens technology.

  • 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
  • 3 ceramic junctions
  • Independent of flow
  • KCl reservoir
  • Alpha glass, medium impedance, universal glass, fluoride resistant

Low-maintenance pH sensors with gel reference electrolyte. The SE558 sensor has an integrated temperature detector to allow automatic temperature compensation of the pH signal during calibration and operation.

The SE558 sensor is particularly suitable for use in media of very low conductivity. It provides 3 ceramic junctions and a KCl reservoir.

Applications
Boiler feed water, condensate, ultrapure water, water supply and distribution, WFI.

We look forward to hearing from you!

Used in Process or Applications

Since steam generators fulfill application-critical functions and the cost of their downtime or replacement is extremely high, damage caused by wear should be prevented by monitoring water quality.
Reverse osmosis systems are used for water treatment in a wide range of industrial applications. The main application is industrial saltwater desalination.
The taste and quality of beer are highly dependent on the quality of the water used for brewing it. It is determined by pH and conductivity measurements.
