ABB 100 GP pH/ORP analog sensor

ABB 100 GP pH/ORP Analog Sensor – Reliable Performance for General Process Applications

The ABB 100 GP analog pH/ORP sensor is engineered for accurate and cost-effective monitoring in a wide range of general-purpose applications, including drinking water, cooling systems, food & beverage production, and municipal wastewater treatment. Designed with a rugged, maintenance-free body, this sensor delivers long-term reliability and reduced operating costs.

Key Features

• Dual Measurement Capability – Configurable for both pH (0–14) and ORP/Redox (-2000 to +2000 mV) measurements.

• Durable Construction – Built with chemical-resistant PVDF (Kynar®) body for harsh industrial environments.

• Double Junction Reference – Advanced design with ion trap protection extends sensor life by preventing electrode poisoning.

• Anti-Fouling Junction – Large PTFE junction resists clogging and ensures easy cleaning.

• Temperature Accuracy – Integrated temperature element provides fast, precise response to process fluctuations.

• Electrode Options –

  • High-Performance (S) glass for full pH range.

  • Low-Temperature (LT) glass for <15 °C processes.

  • Platinum electrode for ORP measurement.

• Flexible Installation – Available in flush or notched body styles to handle fibrous or abrasive applications.
