- 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
Typical Applications:
- Water & wastewater treatment
- Neutralisation systems
- Scrubber control
- Effluent monitoring
- Surface finishing
- Flocculent coagulation
- Heavy metal removal and recovery
- Toxics destruction
- Sanitisation systems
- Pool & spa control
