Specifications and Features
2750 DryLoc pH/ORP Sensor Electronics
The Signet 2750 pH/ORP Sensor Electronics featuring the DryLoc® connector, provides a variety of functions to suit various requirements.
The Signet 2750 pH/ORP Sensor Electronics 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.
The 2750 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 2750 in-line version and are also available as accessories for the submersible 2750.
The 2750 Submersible Preamplifier can also be used as an In-line amplifier when used with the ¾" or 1" threaded sensors including the 2724, 2774 and 2764 series electrodes. The 2750 in-line Preamplifier can be used with Signet fittings up to DN100 (4 in.) and wet-tap assemblies.
