Triplett Test Equipment & Tools’ ET100 GFCI receptacle tester features a push-button test to help validate that GFCI receptacles are operating properly. The color-coded, three-light display helps users pinpoint any one of five potential wiring issues: open ground, open neutral, reversed hot and ground, open hot and reversed hot and neutral. Codes are indicated on both sides of the tester...

Greenlee’s handheld ground-resistance tester reads ground resistance down to 0.10 Ohms. The impedance function is capable of testing four separate frequencies: 50 Hz, 60 Hz, 128 Hz and 2,083 Hz. It operates in temperatures between –4 to 131°F. It includes a calibration loop, and it stores measurements in its memory.

Fluke Corp.’s T6-1,000 electrical tester measures voltage to 1,000V AC through the open fork without test leads. There is no need to open covers or remove wire nuts and it can measure voltage and current. It takes measurements by sliding a single wire into the open fork. The hold button temporarily freezes the reading for easy viewing. On wires up...

AEMC’s 6424 ground resistance tester is designed for testing commercial, residential and light industrial grounding systems. It features an automatic verification of the injector auxiliary rod connection. It measures voltage up to 600V AC/DC. The two- and three-point testing enables measuring of continuity, bonding and ground resistance.

AEMC’s CA7028 wire mapper is a hand-held structured cable mapping and troubleshooting tester designed for use on UTP, STP, FTP and SSTP cabling equipped with RJ-45 connectors. It detects open circuit pairs, shorts, crossed wires and more. If the main unit is plugged into an operational RJ-45 socket, it will give a warning tone and display if a telephone voltage...

AEMC’s 6240 10A micro-ohmmeter is a low-resistance tester for plant maintenance and field use. It is designed to conduct tests on both resistive and inductive material. It includes a polarity-reversal function, a power cord and USB cable. There is a large multifunctional backlit display. There is an overload and input fuse protection with six selectable resistance ranges.
