In-line

2760

DryLoc® Electrodes sold separately.

The Signet 2760 pH/ORP Preamplifiers feature a
DryLoc® connector, providing a robust connection to
Signet DryLoc electrodes.

The 2760 preamplifier allows DryLoc pH/ORP electrodes
to work with Signet ProcessPro® and ProPoint® pH/ORP
instruments.

The DryLoc electrode connector system quickly
forms a robust assembly for submersible and in-line
installations. Optional NEMA 4X junction enclosures
extend the preamplifier cable to long distances.

The 2760 submersible preamplifier can also be used as
an in-line preamplifier when used with the ¾ in. or
1 in. threaded sensors including the 2724, 2774 and
2764 series electrodes. The 2760 in-line preamplifier
can be used with Signet fittings up to DN100 (4 in.) and
Wet-Tap assemblies.

Applications

• Water/Wastewater Treatment

• Neutralization Systems

• Scrubber Control

• E uent Monitoring

• Surface Finishing

• Flocculent Coagulation

• Heavy Metal Removal and Recovery

• Toxic Destruction

• Sanitization Systems

The 2760 pH/ORP preamplifiers are compatible with the
Signet 8750 and older analog transmitters. The 8900
and 9900 instruments and Profibus Concentrator require
the use of the 2751 Smart Sensor Electronics, and are
not compatible with the 2760 preamplifier.
