Description
The Signet 2751 pH/ORP Sensor Electronics featuring DryLoc connector, provides a variety of functions to suit various requirements. The 2751 has a preamplified signal and features two different outputs: a two wire 4 to 20 mA loop output with EasyCal function or a digital (S3L) output which allows for longer cable lengths and is compatible with the Signet 8900 or 9900 instruments, and Profibus Concentrator.
The 2751 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 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 2750.
