M4 Knick SE554 AMSN Combination pH & ORP Sensor

M4 Knick SE554 AMSN Combination pH & ORP Sensor

The SE554 AMSN measures pH and oxidation-reduction potential simultaneously in liquids containing suspended solids. Its construction combines Alpha pH glass, a platinum ORP ring, two open junctions, and a polymer reference electrolyte with concentrated KCl.

Designed for dirty industrial processes, the sensor supports applications involving alkaline liquids and elevated pressure. Integrated temperature measurement supports pH compensation, while Memosens communication enables digital diagnostics and calibration away from the process installation.

Applications

• Liquids containing fine suspended solids

• Caustic dosing systems

• Wet-gas scrubbers

• Slurry handling

• Wastewater clarifiers

• Cooling towers

Features and Memosens Benefits

• Combined sensing provides pH and ORP measurements from one sensor.

• Open junctions suit solids-bearing process liquids.

• Polymer electrolyte reduces routine maintenance.

• Sealed inductive communication helps prevent moisture-related signal problems.

• Electrical isolation reduces interference from ground loops.

• Workshop calibration and diagnostics simplify field servicing.
