  • Portable pH meter for effluents having a self-cleaning electrode chamber
    Patent number: 4285792
    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).
