ORP Sensors

Endress and Hauser – Industrial, Rugged, High Performance ORP Sensors have a built in Internal Plunger, permitting 360 Degree Mounting Orientation. Concave and Flat Head Designs for Bulb Protection are available with Cast-In-Place solid reference electrolyte to maintain a constant reference cell potential.

The Porous Teflon liquid junction resists fouling & chemical attacks, and consist of a Double junction reference cell for increased service life.

Threaded 3/4 inch NPT ends, or Smooth Surface probes as well as options for Submersible Probe Holders, Cables, and wiring terminations. Optional High Temperature Versions are also available.
