HydroFlex Hydrogen Reference Electrode (GAS-81010)
OVERVIEW
HydroFlex is a platinum-hydrogen reference electrode for standard-compliant electrochemical potential measurements. It uses a replaceable internal hydrogen source and contains no internal electrolyte, eliminating ion discharge and diffusion potential while preventing contamination of the measuring electrolyte. Its PTFE construction permits use in concentrated fluoride-containing electrolytes and strongly acidic or strongly alkaline media from pH -2 to 16. HydroFlex is particularly suitable for corrosion measurements and long-term measurements of up to 6 months.
This standard configuration includes the HydroFlex electrode with a hydrogen cartridge, activation sticker and manual. Users requiring an additional hydrogen cartridge, test lead and cartridge tools can select the HydroFlex Starter Kit (Item No: GAS-81000).
