2750 and 2760 pH/ORP Sensor Electronics

Analytical Sensors

SPECIFICATION | CAD DRAWING

• Inline or submersible install
• pH or ORP operation
• Patented DryLoc® connector

Sensor electronics and pre-amplifiers for Signet DryLoc® pH and ORP electrodes with versions for in-line integral mount and submersible installation.
The Signet 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring DryLoc® connectors, provide a variety of functions to suit various requirements.
The 2760 is a pre-amplifier that allows any DryLoc® 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 pre-amplified signal.

The 2750 comes with the same pre-amplified signal as the 2760, but features two different outputs: a two-wire 4 to 20 mA 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 Signet 2750 and 2760 pH/ORP Sensor Electronics features include:

In-line integral mount and submersible installation versions
Automatic temperature compensation
Auto configuration for pH or ORP operation
Optional EasyCal calibration aid
Automatic buffer recognition
Junction boxes for convenient wiring
Compatible with 3719 pH/ORP Wet-Tap
