Reference Electrodes

Standard Hydrogen Reference Electrode HydroFlex®


The easy way of measuring potentials!

This reference electrode works in every electrolyte.

Measurement error sources like liquid junction potentials or contamination of your electrolyte do not occur. Therefore HydroFlex® is perfectly suited for corrosion measurements.

Also long time measurements up to 6 months without any user action belong to the unique features of HydroFlex®.
