Submersion Mounted pH Electrodes From Sensorex

Sensorex Submersible Flat-Surface, Self-Cleaning pH and ORP Electrodes

The submersion pH and ORP electrodes from Sensorex are designed for measurements in tanks, flumes and sewer lines. Submersion designs are also well suited for high suspended solids applications, flocculation operations which require low velocities, or in tanks with high agitation.

Where low velocities are present and coating is a problem, the electrode can be mounted at a 45 degree angle facing into the flow so as to obtain increased scrubbing action across the measuring surface.
The cartridge quick disconnect design makes changing electrodes a snap and minimizes down time due to electrode maintenance.

Model S651CD offers a pH glass protection feature and the extra performance of acrylamide reference gel.

  • Quick disconnect design saves time and money

  • Installs in seconds, no tools necessary

  • Flat surface design resists coating

  • CPVC or PVDF models available

  • Available with or without ATC elements


  • Range: 0-14pH (0-12pH without Na+ error) +/- 2000mV for ORP

  • Wetted Materials:
    Body/Junction: CPVC/HDPE ("-CD" models) PVDF/ Porous PVDF ("-KD" models)
    Measuring Surface: pH glass (pH), Platinum or Gold (ORP)
    O-rings: Viton
    Gasket: EPR

  • Temperature/Pressure Range:
    (all models ending in "-CD") = 0C* - 75C (0-100psig), 80C (0-85psig)
    (all models ending in "-KD") = 0C* - 100C (0-100psig)
    Note: From 0 to 10C, electrodes will exhibit slower response time.

  • Reference Type: Ag/AgCl, Sealed Double Junction
