AstroAI ETK2 Electrical Test Kit with Non-Contact Voltage and GFCI Testers

Dual voltage-detection modes and a dedicated GFCI outlet tester help you check circuits and outlets with one compact kit. The AstroAI ETK2 combines a non-contact voltage tester with an outlet tester for practical home wiring checks, circuit diagnostics, and routine GFCI testing.

A backlit LCD, built-in flashlight, and screwdriver bit make it easier to handle checks and basic panel adjustments in one setup. How can you get a clearer picture of both voltage and outlet wiring? Use the two testers for their respective checks, with the display and audible buzzer providing useful feedback as you work.

What you’ll notice day to day

The non-contact tester offers two sensitivity modes: 12–1000V AC and 70–1000V AC. That gives you options for voltage detection across different checking tasks, while the LCD presents an analog bar, percentage, and buzzer volume. A built-in flashlight and backlit display help keep the readings visible in dim areas such as utility spaces or near electrical panels.

The tester also has a built-in screwdriver bit for removing or tightening panels, so a basic adjustment does not require reaching for a separate screwdriver. For outlet checks, the included GFCI tester checks wiring conditions and lets you test GFCI functionality. Compared with assembling separate testers for these tasks, this kit brings both types of checks together in one compact set.

What matters most

This is a two-tool kit, not just a voltage pen: it includes the VTS1000H non-contact voltage tester and a GFCI outlet tester. That pairing suits everyday electrical checks around the home, including monthly GFCI testing, locating wire breakpoints, and safety checks before replacing switches or outlets. The tester’s analog bar, percentage display, and buzzer volume give you several ways to read its indication during breakpoint testing.

For homeowners and DIY users, the combination supports routine checks without requiring a separate purchase for each tester type. Electricians can also keep the compact kit available for quick diagnostic tasks. Its drop-resistant construction is designed for regular handling, and the 5-minute auto-off function shuts the voltage tester down after use.

How to use it

Choose the voltage tester’s sensitivity mode for the check, then use its non-contact detection to locate voltage or investigate a possible wire breakpoint. Read the LCD and listen to the buzzer as you move through the area being checked. In low light, switch on the built-in flashlight and use the backlit display to view the information.

Use the separate GFCI outlet tester to check outlet wiring conditions and test GFCI functionality. Before replacing a switch or outlet, use the kit for the relevant safety checks as part of your electrical work. The integrated screwdriver bit can help with panel removal or tightening when needed.

Should you buy it?

It’s a great fit if you want one home tool set for both non-contact voltage detection and GFCI outlet checks. The dual sensitivity modes, readable LCD, low-light features, and built-in screwdriver bit support a range of practical diagnostic tasks, while the outlet tester adds a separate way to check wiring and GFCI function. Choose the AstroAI ETK2 for a compact kit that brings these everyday circuit and outlet checks together.
