Product Description

Multifunctional Chromium Vanadium Dual Voltage Test Screwdriver and Voltage Tester

1. Product Name and Brief Overview

Main Name: Multifunctional Dual-Range Voltage Tester and Screwdriver

Descriptive Name: Professional Chromium Vanadium Steel AC/DC Voltage Detection Screwdriver

General Name: Smart Electronic Test Pen with Visual and Audible Alarms

This professional multifunctional test screwdriver is an essential tool for electricians, technicians, and DIY enthusiasts. It perfectly combines the functions of a precision screwdriver and a reliable voltage tester. Made of high-quality chromium vanadium steel, it is durable, high-performance, and suitable for various electrical testing and repair tasks.

2. Key Features

Dual Voltage Range Detection: Safely and accurately detects low voltage (12V-48V AC/DC) and standard voltage (110V-250V AC/DC), clearly displayed by independent LED indicators.

Superior Materials: The screwdriver tip is forged from chromium vanadium steel (Cr-V), possessing excellent hardness, wear resistance, and torsional strength.

Multifunctional 2-in-1 Design: Can be used as both a voltage tester and a slotted screwdriver, saving toolbox space.

Clear Visual and Auditory Indicators:

Red LED Indicator: Illuminates during standard voltage ranges (110V-250V).

Green LED Indicator: Illuminates during low voltage ranges (12V-48V).

Buzzer Alarm: A buzzer sound (on some models) provides additional confirmation when voltage is detected.

Direct Contact and Inductive (Non-Contact) Testing:

Contact Testing: Accurately reads voltage by directly contacting the pen tip with a conductor.

Inductive Testing: No direct contact required; simply insert the pen tip into a live hole or into the insulation of a wire to detect the presence of voltage in a wire or socket.

Built-in Insulation and Safety Protection: Equipped with finger cots and a fully insulated pen body to prevent accidental electric shock.

Pocket Clip and Retractable Tip: Features a convenient pocket clip and a retractable tip cover for safety when not in use.

3. Detailed Function Description

This smart test pen features a simple and efficient design:

Low Voltage Test (12V-48V AC/DC):

Touch the metal tip of the screwdriver to the point to be tested.

Place your thumb on the metal contact at the end of the handle.

If a voltage within the 12V-48V range is detected, the green LED indicator will light up.

Standard Voltage Test (110V-250V AC/DC):

Repeat the above steps.

If a voltage within the 110V-250V range is detected, the red LED indicator will light up. Some models will also emit a beeping sound.

Inductive (Non-Contact) Breakpoint Test:

Place your thumb on the end contact.

Bring the probe close to an insulated wire or insert it into the neutral/live wire hole of a socket.

The tester senses electromagnetic fields; if voltage is detected, the red/green LED indicator will light up, identifying live wires without stripping the insulation.

Screwdriver Functions:

The robust chrome vanadium steel probe is perfectly sized for common slotted screws, allowing you to tighten/loosen screws immediately after testing.

4. Technical Specifications

Material: Chrome vanadium steel (tip), ABS/insulating plastic (body)

Voltage Range: 12V-48V AC/DC (low voltage), 110V-250V AC/DC (standard voltage)

Indicator Lights: Dual-color LED (red/green) + buzzer (some models)

Screwdriver Bits: Flathead/slotted (e.g., 3mm x 75mm)

Safety Standards: Complies with international electrical safety standards (e.g., IEC/EN standards).

Power Supply: Typically uses 2 AG13 or LR44 button batteries (included).

5. Safety Warnings and Precautions

Always ensure the tester is connected to a live power source before use.

Do not use in circuits exceeding the rated voltage (e.g., 250V AC).

When testing, ensure your hands are dry and stand on a dry, insulated surface.

If the LED indicator dims, replace the battery immediately to ensure accurate readings.

This tool is only for low-voltage and standard household voltage testing. It is not suitable for high-voltage industrial applications.

Keep the tool clean and dry. Store it in a safe place out of reach of children.
