The new Megger two wire 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.

The new LTW300’s offer a range of features to make earth loop testing safer and easier.

The range consists of:

LTW315 - 2 Wire loop impedance measurement

LTW325 - 2 wire + maxZ + (R1+R2)

LTW335 - 2 wire + maxZ + (R1+R2) + Download

LTW425 – 2 wire + maxZ + (R1+R2) + 0.001 Ω
