The ultimate 16th edition instrument

Following many months of careful planning and development, the Socket & See DL 420 is said by the company to be 'the best loop tester available for the discerning electrical engineer'.

Being sensibly priced in the famous Socket & See easy-to-use tradition, the DL 420 is a four in one digital tester with loop, including PFC (Prospective Fault Current), mains voltage, correct wiring and correct polarity with patented non-trip technology. The instrument uses the true impedance technique for accurate measurement of loop and PFC at origin.

With a carrying case included, it is fully protected against accidental phase to phase connection. The tester has a built in SOK 32, correct wiring indication, accurate mains voltage measurement to the latest BS 7699 and provides the novel Socket & See polarity test which gives the ultimate overall system safety check.
