GF+ Signet 3-2751-2 Smart Sensor Electronics for Signet pH/ORP electrodes

The GF Signet 2751 pH/ORP smart sensor electronics feature field free calibration, out of range glass impedance, and broken glass detection to alert the operator to probe failure or maintenance needs.

It self-configures for pH or ORP operation via automatic recognition of the electrode type. The optional EasyCal feature allows simple push-button calibration and includes an LED indicator for visual feedback.

The 2751 has a preamplified signal and features two different outputs: a two-wire 4 to 20mA loop output with EasyCal function or a digital (S3L) output which allows for longer cable lengths.

The DryLoc electrode connector quickly forms a robust assembly for submersible and in-line installations. NEMA 4X junction enclosures are integral parts of the 2751 in-line version and are also available as accessories for the submersible.
