Multifunctional Three-Speed Voltage Tester for Safe AC Detection

This electromagnetic induction tester is designed for electricians and home users who need to identify live wires quickly and safely without direct contact. With a detection range covering AC 24-1000V and an adjustable three-speed sensitivity, it adapts to various wiring environments. The sound and light alarm ensures you never miss a detection, even in noisy or dim conditions. Made from durable ABS material in a bright yellow casing, this tool is built for practical electrical troubleshooting and safety verification.

Features and Construction

The tester combines multiple detection modes in one compact handheld device. Its adjustable sensitivity and wide voltage range make it suitable for residential and light commercial electrical work.

Three-Speed Sensitivity

The three-speed adjustment allows you to set detection sensitivity based on the environment. Higher sensitivity for finding cables behind walls, lower sensitivity to pinpoint specific wires in a crowded panel.

Voltage and Frequency Range

AC voltage detection from 90-1000V (red light) and 24-1000V (green light) covers standard mains voltages in most countries. The 50-500Hz frequency range matches common AC power systems.

Sound and Light Alarm

A combined sound and light alarm activates when voltage is detected, providing clear feedback. The low pressure reminder alerts you when battery power is low to avoid false readings.

Uses and Placement

Used in electrical inspections, maintenance, and DIY projects. Its non-contact nature reduces shock risk while troubleshooting circuits.

Professional Electrical Work

Electricians can use it to verify that circuits are live before working, or to trace wires in junction boxes. The neutral/fire line judgment feature helps distinguish phase from neutral conductors.

Home DIY and Repairs

Homeowners can safely check for live wires before drilling into walls, or identify which breaker controls a specific circuit. The compact size fits in a tool box or pocket.

Benefits and Buying Value

This tester combines multiple functions (voltage detection, neutral/fire line judgment, low battery alert) in one device, reducing the need for separate tools. Its adjustable sensitivity provides flexibility for various tasks.

Battery Powered Portability

Runs on three standard AG10 batteries (1.5V, not included), making it convenient for use in the field without a power cord. Low pressure reminder ensures users replace batteries before accuracy is compromised.

Durable ABS Construction

The yellow ABS casing is lightweight yet impact-resistant, suitable for daily use on job sites. Its compact dimensions (144 x 26 x 16 mm) make it easy to handle and store.
