Specifications and Features
Signet 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 2750 has a preamplified signal and features two different outputs: a two wire 4 to 20 mA loop output with EasyCal function or a digital (S3 L) output which allows for longer cable lengths and is compatible with the Signet 8900 Multi-Parameter Controller. 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 preamplifier when used with the 3/4” 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.
