ABB 100 GP Series pH and ORP Sensors: Analog & Digital Solutions

When municipal water facilities and industrial plants across Eastern Canada require reliable, cost-effective water quality monitoring, choosing the right instrumentation is critical. As a trusted strategic partner, Everest Automation provides the complete lineup of ABB pH/ORP sensors, anchored by the versatile 100 GP series. Available in both traditional analog configurations and advanced digital formats, the 100 GP family delivers exceptional performance for general-purpose water applications.

Understanding the 100 GP Platform: Analog vs. Digital

Selecting the right deployment format depends entirely on your plant’s control architecture. Both options share the same rugged physical construction, proprietary high-performance glassware, and maintenance-free design philosophy:

Platform Format Technical Description
ABB 100 GP (Analog) The ideal solution for standard installations requiring direct connection to traditional control systems via tinned leads, BNC, or VarioPin terminations. It offers dependable electrochemical measurement for everyday water quality tracking.
ABB 100 GP-D (Digital) Incorporates plug-and-play digital technology via EZLink that automatically uploads calibration, diagnostic, and manufacturing data to any compatible ABB transmitter within seconds, dramatically reducing commissioning time.

Engineered for Maximum Efficiency and Longevity

The 100 GP platform is engineered to tackle common measurement challenges such as electrode fouling, thermal shock, and chemical poisoning. Key technical advantages include:

  • Enhanced Double Junction Design: Featuring a polymerized gel electrolyte and a chemical inhibitor combined with an ion-trap, the 100 GP slows down ion-diffusion rates to protect the reference against aggressive poisoning.
  • Superior Fouling Resistance: A large, porous, chemically resistant PTFE junction incorporating Viton seals prevents process buildup, making routine cleaning straightforward.
  • Proprietary Glass Formulations: Utilizing specialized high-performance glass to deliver fast response times without sacrificing mechanical durability, including low-temperature (LT) blue glass options for cold wastewater.
  • Close-Coupled Temperature Tracking: Features an integrated temperature element positioned for instantaneous response to combat thermal drift and maintain precision.

Flexible Body Styles and Intelligent Accessories

To accommodate diverse piping layouts and prevent physical damage in harsh streams, these sensors are available in specialized body configurations:

Flush-Body Design: Paired with flat-shaped glass electrodes to promote natural self-cleaning when installed perpendicular to the sample flow, eliminating fibrous buildup.
Notched-Body Design: Provides physical protection for bullet-style glass electrodes deployed in abrasive measurement conditions.

Furthermore, these sensors utilize universal 3/4 in NPT threaded bodies that integrate seamlessly with modular accessories like flow cells and dip pole assemblies. Review complete engineering details directly on the official ABB 100 GP Analog Sensor Page and the ABB 100 GP-D Digital Sensor Page.
