Smart Pen-style multimeter | Combination voltage tester and multimeter | NCV non-contact voltage detection

Are you still carrying around a bulky traditional multimeter? Are you still relying on experience to identify live wires with an old-fashioned voltage tester?

The Chenzhoudao A6S pen-style multimeter features an integrated pen-shaped design, weighs just 38 grams, and fits into a work pocket just like a ballpoint pen. It combines the high-precision measurements of a digital multimeter with the convenience of a voltage tester, and is specifically designed for electricians, maintenance technicians, home improvement professionals and electronics enthusiasts.

The global pen-style multimeter market is projected to grow at a compound annual growth rate (CAGR) of 10.3% between 2025 and 2031, with smart and portable features becoming key trends in electrical tools. The A6S is the ideal choice in line with this trend.

[Key Features]
🔹 Smart Recognition · Automatic Range Selection
There is no need to manually switch between complex ranges; the A6S automatically recognises measurement parameters such as AC and DC voltage, resistance and continuity. Simply pick it up and start measuring—even beginners can get to grips with it quickly, putting an end to the hassle of ‘selecting the wrong range and blowing a fuse’.

🔹 NCV Non-Contact Voltage Detection
Select NCV mode and simply bring the device close to an AC voltage source to detect it—the closer you get, the faster the beeping becomes. There is no need for direct contact with live parts, making voltage testing safer and more reliable.

🔹 Circuit Break Detection
Move the device along a circuit in NCV mode to precisely locate breaks based on changes in signal strength—the beep becomes faster when a signal is present, and stops when the signal disappears at a break point.

🔹 Six-in-One All-Round Measurement
Function    Range    Resolution    Accuracy
AC Voltage    4V–600V    1mV    ±(1% of reading + 5 digits)
DC Voltage    4V–600V    1mV    ±(1.5% of reading + 5 digits)
Resistance    4kΩ–40MΩ    1Ω    ±(2% of reading + 10 digits)
Capacitance    4 nF–4 mF    1 pF    ±(6% of reading + 10 digits)
Frequency    40 Hz–4 MHz    0.01 Hz    ±(1.5% of reading + 10 digits)
Continuity buzzer    —    —    Automatic detection; beeps when continuity is detected
🔹 Practical Application Scenarios
Domestic electrical repairs: Socket voltage testing, circuit continuity checks
Industrial equipment maintenance: motor winding testing, control circuit troubleshooting
Automotive circuit diagnostics: battery voltage testing, sensor signal measurement
Electronic device repair: motherboard voltage testing, capacitor and resistor measurement
Renovation wiring inspection: live and neutral wire identification, locating circuit breaks

[Product Highlights]
✧ Pen-style design for easy operation in confined spaces

The pen-style design allows you to easily reach into confined spaces such as distribution boxes and equipment compartments for measurements. No longer a bulky traditional multimeter, but a ‘digital pen’ that fits comfortably in your hand.

✧ High-definition backlit display + torch lighting

Working in dark environments is no longer a challenge. The high-definition backlit display ensures clear readability of measurements, whilst the built-in LED torch illuminates the measurement target, allowing you to work with ease even deep within distribution boxes.

✧ Low power consumption + automatic shut-off

Supplied with two AAA batteries as standard, the device automatically switches off after 15 minutes of inactivity, effectively extending battery life. The low-battery alert function keeps you informed of the battery status at all times.

✧ Data hold for more convenient readings

A single press locks the current measurement value, eliminating the need to take notes whilst measuring—particularly suitable for use in low-light or awkwardly angled environments.

【User Guide】
Voltage Measurement (AC/DC Auto-Detection)
