Megger 1006-449 DPT1-C Duplex Connect Twist Probe
What is the Megger DPT1-C Duplex Connect Twist Probe?
The Megger DPT1-C Duplex Connect Twist Probe (1006-449) is a precision test probe designed for UK industrial electricians, commissioning engineers and low-resistance testing technicians using Megger DLRO instruments.
Its twist-to-lock mechanism and sprung dual-tip action deliver a secure Kelvin connection for accurate four-terminal DLRO measurements on switchgear, busbars, earth bonds and bolted joints.
Engineered for demanding industrial environments, it provides the reliable, stable test contact technicians need during high-current bonding and low-resistance testing.
How does the DPT1-C help on site?
The probe’s sprung twisting tips compress and rotate as they make contact, applying 2.4 kg of spring force to improve grip and cut through oxidation, paint or contamination on metal surfaces.
Each tip is hardened, tempered and ground into a square profile, giving four precise edges that bite into the test piece for a cleaner, more reliable connection.
Inside the probe, an innovative volute spring maintains a consistent electrical path without needing a traditional current-carrying brad, improving durability and long-term reliability.
With 14 mΩ resistance from connector to tip, a 10 A rating and 10 mm P-to-C spacing, the DPT1-C is built for precision low-ohm measurements where stable contact and repeatability matter.
Compatible with any Duplex Connect test lead or extension lead, it integrates seamlessly into DLRO test setups.
For safety, the probe is intended for <30 V circuits only.
