Description

ZU6985 4-Electrode Conductivity Sensor | Glass Tube | Large measuring range 1 μS/cm ... 1 S/cm

4-electrode conductivity sensor

  • Easy to use
  • No platinization required
  • Large measuring range: 1 μS/cm ... 1 S/cm
  • Simultaneous temperature measurement
  • High chemical resistance (materials: glass, platinum, PTFE, FKM)
  • Virtually resistant to contamination
  • Immediately ready for measurement thanks to individually measured cell constants

The sensor has a very large measuring range from 1 μS/cm to 1 S/cm and is equipped with a quick-reacting Pt1000 temperature detector.  

It has a glass/platinum 4-electrode measuring system with an easy-to-re-place precision glass tube, is simple to clean, and does not require platinization.

Applications
Precise measurements in a broad conductivity range in the laboratory or during portable use – the resistant materials also permit use in media with serious chemical stress.
