Mini-HydroFlex Pro Hydrogen Reference Electrode (GAS-81030)
OVERVIEW
Mini-HydroFlex Pro is a compact, pressure-resistant hydrogen reference electrode designed for electrochemical applications under pressure and for installations with limited space. Its redesigned PP head incorporates an industry-standard 1/4"-28 UNF thread and a top-mounted, gold-plated 2 mm electrical contact. The electrode is recommended for use with the ElyFlow cell fitted with a PEEK analyte compartment.
The electrode uses a replaceable internal hydrogen source and contains no internal electrolyte. This prevents ion discharge, diffusion potential and contamination of the measuring electrolyte. Mini-HydroFlex Pro can support long-term measurements for up to 12 months without user intervention.
