Retractable Fitting

Stainless-steel ball-valve fitting with integrated 2-electrode sensor for conductivity measurement


  • large measuring range from 10 nS/cm to 1000 μS/cm
  • integrated temperature detector
  • retractable fitting with robust ball valve
  • long insertion length of the sensor in the process
  • safe and easy handling
  • maintenance, cleaning, and replacement of the sensor during the running process
  • sensor movement up to process pressures of 6 bars possible
  • safe sensor locking in process position with bayonet locking mechanism
  • high level of process safety due to durable materials and robust design

Robust retractable fitting with ball valve. The coaxial conductivity sensor integrated in the immersion tube has a large measuring range from ultrapure water to 1000 μS/cm. After retraction of the immersion tube, the sensor can be serviced, cleaned, or replaced during the running process. The outer electrode is replaceable. A temperature detector is integrated in the sensor for exact temperature compensation.
