The Signet 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring connectors, provide a variety of functions to suit various requirements.
The 2760 is a preamplifier that allows any pH/ORP electrode to work with most Signet instruments. It is also sold as a simple connector for use with other manufacturers' instruments that do not require a preamplified signal.
The 2750 comes with the same pre-amplified signal as the 2760, but features two different outputs: a two-wire 4 to 20mA loop output, or a digital (S3L) output which allows for longer cable lengths and is compatible with the Signet 8900 Multi-Parameter Controller. The 2750 devices self-configure 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 electrode connector found on both models 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 both Models 2750 (submersible version) and 2760.
