Socket & See PDL234 Plus Part P Loop Testing Kit
4-in-1 No-Trip Loop Tester for Loop, Voltage, Wiring and Polarity Checks
The Socket & See PDL234 Plus Part P Loop Testing Kit combines four essential electrical checks in one compact tester, allowing electricians to test loop impedance, mains voltage, correct wiring and polarity using a single instrument.
Bright LEDs provide clear indication of test results, while the built-in SOK32 socket tester identifies correct and faulty wiring conditions. The PDL234 also incorporates Socket & See‘s patented no-trip loop test technology, making it particularly useful when carrying out loop testing on circuits where unwanted RCD tripping needs to be avoided.
For additional protection, the Socket & See PDL234 is designed to withstand accidental phase-to-phase connection. Its polarity test pad can also detect a network supply live-earth or live-neutral reversal, providing an additional check of the electrical supply.
Supplied as a complete kit with fused test leads, a 13A plug to IEC female connector and carry case, the PDL234 Plus Part P Loop Testing Kit provides a practical solution for professional electrical testing.

Why Choose the Socket & See PDL234 Plus?
The Socket and See PDL234 Plus brings several commonly required electrical tests together in one straightforward instrument, helping reduce the need to switch between separate testers.
Its no-trip loop testing operates using a three-wire Phase-Neutral-Earth connection with a test current below 15mA at 253V AC. Five loop resistance indication points cover readings from below 1Ω through to above 200Ω.
For mains voltage testing, the PDL234 categorises the measured Phase-Neutral voltage through three LED ranges: below 207V AC (LOW), 207–253V AC (STANDARD), and above 253V AC (HIGH).
