4 Signet 2750 DryLoc pH/ORP Sensor Electronics
Use standard installation
hardware to connect the
submersible 2750-3 or -4
directly to external equipment.
1/2 in. NPT threads
The 8052-1 NPT Mount Junction box
(or 8052-2 with EasyCal) connects to
3 /
4
in. pipe or conduit and provides
convenient wiring termination.
The 8050-1 Universal Mount junction
box (or 8050-2 with EasyCal) mounts
fl at onto a wall or can be strapped to
a post or pipe.
2750-3: 3/4 in. NPT threads

1. Insert electrode into base
of the 2750-3 or 2750-4
and turn until keyed
contacts are seated.
2. Thread retaining cap over
electrode and hand-tighten
onto 2750.
3. Attach 3 /
4
in. watertight pipe to the top of the 2750.
Secure the threaded connection to prevent any leakage.
• For additional defense against possible accumulation of
condensation at the back seal area of the sensor, fi ll the
lower 3-4 inches (75-100 mm) of conduit or extension
pipe with a fl exible sealant such as silicone.
