Mini-HydroFlex Hydrogen Reference Electrode (GAS-81020-v02)
OVERVIEW
Mini-HydroFlex is a reduced-size hydrogen reference electrode developed for applications in confined spaces. Its structure and function correspond to the HydroFlex electrode, but its shaft diameter is only 1.6 mm. Mini-HydroFlex can be used in almost any electrolyte and is recommended for use with FlexCell and ElyFlow electrochemical cells.
The electrode contains a replaceable internal hydrogen source and no internal electrolyte, eliminating ion discharge and diffusion potential while preventing contamination of the measuring electrolyte. It is particularly suitable for corrosion measurements and long-term measurements of up to 12 months.
