Megger LTW315 Impedence Tester
Model No :
Megger LTW315
Part Code :
LTW315-EU-BS

Overview

The 2 wire non-tripping earth loop testers verify the loop impedance of a live electrical circuit, ie without the need to disconnect the electrical supply. The new LTW300 series instruments offer a 2 wire loop testing solution that does not trip 30 mA RCDs and can be used on a wide range of voltages.
