Bypass Fittings for Sensors

Your sensors are ideally accommodated in the bypass fitting. This fitting ensures optimum measuring conditions.

In-flow measurement

We offer a range of bypass fittings for specific integration into processes. They hold potentiometric and amperometric sensors as well as conductivity sensors and ensure optimum operating conditions for measurement.

DGM Modular In-Line Probe Housing

Modular in-line probe housing type DGM to hold conductivity, Pt 100, pH or ORP sensors with PG 13.5 screw-in thread or amperometric sensors with R 1" screw-in thread.


  • Simple installation (completely ready mounted on a panel); max. 7 modules on a panel
  • Simple retrofit extension option (see extension modules)
  • Module for sample water flow control
  • Quick measurement recording due to low volume of sample water
  • Each completely assembled DGM is equipped with a simple sampling tap

Ball valves on both sides for shutting off the flow and for flow adjustment.

With this: Sampling tap, extension modules, connection line, ball-type stopcock, sensor mounting kit and other accessories.
