Martindale EZ150 Earth Loop Socket Tester

This inventive product can claim to be the first socket tester to include measurement of earth loop impedance. Conventional socket testers will only indicate the presence of an earth, however if the socket has a dangerously high earth resistance, they will not be able to identify this. Using the EZ150 gives you the peace of mind that not only is the socket wired correctly, but also the earth resistance is within acceptable levels. Martindale's T-SafeTM technology is incorporated into the EZ150, in order to ensure that RCDs will not trip when the loop impedance check is carried out. Earth loop measurement, and socket faults, are all indicated with bright, long-life LEDs. This unit should be used as an indicator only and not to provide readings for completion of certificates.
