ABB pH/ORP Sensors – Reliable Solutions for Industrial Water & Process Applications

ABB pH/ORP sensors are advanced electrochemical instruments designed to measure both pH (acidity/alkalinity) and oxidation-reduction potential (ORP) in liquids. These sensors ensure precise monitoring and control of chemical properties across industries such as water treatment, power generation, pharmaceuticals, food & beverage, pulp & paper, and chemical processing.

How ABB pH/ORP Sensors Work

  • pH Measurement: A glass electrode detects hydrogen ion concentration, indicating whether a solution is acidic or alkaline.

  • ORP Measurement: A platinum or inert metal electrode measures the solution’s ability to gain or lose electrons, reflecting its oxidizing or reducing potential.

Key Features & Technologies

  • Digital Sensors with EZLink: Plug-and-play installation with automatic calibration and diagnostics upload.

  • Rugged Electrodes: Solid-state reference technology prevents clogging, poisoning, and fouling in harsh environments.

  • Application-Specific Glass Types: Options include standard, high-performance, low-temperature, and hydrofluoric acid-resistant glass.

  • Flexible Designs: Available in immersion, insertion, retractable, and flow-through models to suit diverse industrial needs.

Typical Applications

  • Water & Wastewater Treatment – Municipal and industrial systems

  • Chemical Processing – Process optimization & safety control

  • Food & Beverage – Ensuring product consistency & quality

  • Pulp & Paper Industry – Continuous monitoring of processes

  • Power Plants – Maintaining water quality in boilers & cooling systems

  • Pharmaceuticals – Precise monitoring of critical processes
