Amprobe's VPC-10A handheld residential and commercial voltage and continuity tester measures AC and DC voltage in circuitry and its components, including outlets, light fixtures and extension cords, while testing the continuity of fuses and light bulbs. Seven LED indicators differentiate voltage levels.

Klein Tools’ noncontact voltage tester detects 70V–1,000V AC in cables, cords, circuit breakers and more. It is dustproof and waterproof with an IP-67 rating and 9.8-foot drop protection. The bright green LED indicates the tester is powered on, and, when voltage is detected, a bright red LED illuminates and an audible tone will sound.

Amprobe’s GP-2A ground resistance resistivity tester measures earth ground resistance—three-point (fall of potential) or two-point tests. Automatic voltage measurement prevents false measurements, and it automatically applies three testing frequencies for accurate readings.

Ideal Industries’ 61-657 dual-range noncontact voltage tester can sustain a drop from 6.6 ft. and provides noncontact voltage detection through an antenna enclosed in plastic at the tip of the tester, which senses the presence of the electromagnetic field around live conductors. The tip is illuminated by a green LED when powered on and switches to a red flashing LED and audible beep that increase in frequency as the voltage level increases.

AEMC’s CA7028 wire mapper is a hand-held structured cable mapping and troubleshooting tester. It detects open circuit pairs, shorts, crossed wires, crossed pairs, reversed pairs, split pairs and shield faults. If the main unit is plugged into an operational RJ-45 socket, it will give a continuous warning tone and display if a telephone voltage is present on any of the pins.

Amprobe’s DGC-1000A clamp ground resistance tester has a continuity beep if the resistance is lower than 40 ohms. It provides True-RMS current measurement including leakage current. Users can select high or low Ohm audible alarms. There is an onboard memory and data logging feature.

Fiber Instrument Sales’ OF1000UF visual fault locator identifies breaks and macro bends. It is for single- and multimode applications and is designed for fiber end identification. It features 1 mW fiber-coupled laser, 650 nm visible red light and a protective rubber boot.

Megger’s LT300 high current loop tester offers high current loop testing over a wide range of frequencies and supply voltages with a two-wire operation. It has a large clear display that aids visibility in poor conditions. It features a 16–400 Hz operation.
