FLS pH/ORP 400

Glass body Bulb electrodes

This FLS line of pH/ORP electrodes with glass body has been designed to fit a wide range of applications.
Different type of junctions guarantee to find the proper solution in according with application needs: version with open junction for a fast response time, version with ceramic junction useful for high pressure application.

Moreover it’s available a version with a special barriered single junction which combine the typical short response time of standard single junction and the contamination protection of reference solution typical of double junction.

A dedicated version for high temperature application is present in our range.

Version with outline cable or with head connection (S7) are available also.
