Industrial valves for pH measurements

pH measuring armature for in-line measurements

Medium wetted parts made of CrNi steel. Attachment in pipes through welding socket.

Benefit: Removal, cleaning and calibration of the electrode is possible without interrupting the working pressure.

To do so, the electrode's measuring flask is moved back and closes towards the medium's pressure side. After calibration, the measuring flask is again moved into the system and assumes again the measurement.

Construction height of fitting: approx. 300 mm
