The J3675 pH or ORP controller with 3 digit LCD display features (2) 5 amp relays in a 1/4 DIN panel mount format and has been long known as an industry workhorse.
Two relays may be used for pH control to manage both acid and base injection in order to maintain pH within a specified range. ORP reads in 1mV resolution and is used to control an Oxidation or Reduction reaction typically for Chlorination, De-chlorination, Cyanide Oxidation or Chrome Reduction.
