Abstract
A self-cleaning apparatus (10) for the monitoring of pH in an effluent process stream (17) includes a sump pump (16) for sampling the effluent process stream (17), a housing (12) for supporting a pH electrode (13), and a cleansing assembly (15) for automatically cleansing the pH electrode (13) entirely powered by the impingement of the fluid process stream (17) upon the cleansing assembly (15). The housing (12) includes an electrode chamber (14) into which the pH electrode (13) extends. The electrode chamber (14) receives the effluent process stream (17) sample from the sump pump (16) and is also automatically, continuously cleansed by the cleansing assembly (15).
