Greenlee’s CS-5000 circuit seeker features an auto-gain option to automatically seek the strongest signal, identifying the target breaker. It supports transmitter-to-receiver distances up to 4 miles for closed-circuit tracing. It is rated for 600V AC/DC.

Klein Tools’ 1,000V AC dual-range noncontact voltage tester detects voltage with simultaneous visual and audible voltage indicators. The auto power-off feature conserves and extends battery life. The screw-thread battery cap with O-ring ensures protection against dust and water ingress. The green light indicates no voltage. It has a pocket clip.

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.
