GF Signet 2751 GF PH Sensor

The GF Signet 2751 GF PH sensor is a smart sensor for measuring pH and ORP (Oxidation-Reduction Potential) in water. Here’s a breakdown of its key features:

  • Intelligent Diagnostics: Performs calibration without removing the sensor (field-free calibration). Detects out-of-range glass impedance and broken glass for proactive maintenance. Automatically configures for pH or ORP based on the electrode type.
  • Simple Calibration (Optional): Offers an EasyCal feature for push-button calibration with LED feedback.
  • Reliable Signal Transmission: Preamplified signal for better noise immunity. Two output options: 4-20mA loop output with EasyCal (for shorter cable lengths). Digital (S3L) output for longer cables and compatibility with Signet instruments (8900, 9900) and Profibus Concentrator.
  • Durable Construction: The DryLoc connector ensures a watertight seal for submersible and in-line installations. NEMA 4X junction enclosures protect the electronics (integral for the in-line version, optional for submersible).
  • Versatile Mounting: Submersible preamplifier can be used in-line with specific sensors (2724, 2734, 2774, 2764 series) and Signet fittings (up to DN100). Compatible with wet-tap assemblies.
