Installations which require continuous potential monitoring will use Reduced Diameter Reference Electrodes
permanently installed in the sand bed. EDI’s SlimLine™ Reference Electrode (Model US) has a 30 year design life and is considered the premium reference electrode for this application. Choose the Extended Life version (Model US50) with a 50 year design life for projects where a longer service life would be beneficial. Some engineers prefer using our Dual Element Reference Electrode (Model UD) with a 30 year design life Cu/CuSO4 (or Ag/AgCl) gelled element along with an encapsulated zinc element.
