Can the DUKA ATuMan Q2 measure in inches and feet?

Yes, the DUKA ATuMan Q2 electronic ruler supports instant unit conversion, allowing you to seamlessly switch between centimeters (cm), inches (in), and feet (ft) via the device settings.

Is this digital roller better than a standard metal tape measure?

The digital roller is vastly superior for measuring curved surfaces, irregular objects, and body circumferences, whereas a standard metal tape measure is rigid and only suitable for straight, flat lines.

How do I charge the electronic ruler and how long does the battery last?

You can charge the electronic ruler using the built-in Type-C port with any standard USB charger; a full charge provides an impressive 180 days of standby time.

Can I test this electronic ruler before buying in Hong Kong?

Yes, you are highly encouraged to visit our Sun Cheong Computer Co. Ltd. physical store in Sham Shui Po, where you can test the rolling mechanism and digital display in person.

Why does my box say ATuMan instead of DUKA?

DUKA and ATuMan are two brand names owned by the exact same parent company, so the product inside is identical regardless of which logo is printed on the external packaging.

Full Product Description

Measure Any Surface with Rolling Precision

The DUKA ATuMan Q2 Mini Digital Electronic Ruler utilizes a smooth rolling wheel to accurately measure flat, curved, and irregular surfaces up to a massive cumulative distance of 99.9 meters. Unlike rigid metal tape measures that struggle with round objects or soft fabrics, this digital roller glides effortlessly over any contour. Whether you are measuring waistlines for custom clothing, checking the diameter of a cylindrical pipe, or calculating the dimensions of a curved sofa, this tool delivers millimeter-level precision (±0.5% accuracy) instantly on its digital screen.

Smart Memory & Auto-Calculation

This electronic ruler eliminates the need for manual math by automatically adding or subtracting your current measurements in real-time. The DUKA ATuMan Q2 features a built-in historical record function, allowing you to store and review past measurements with a simple short press of the power button. This smart memory system completely replaces the need for carrying a paper and pencil on the job site, streamlining your workflow and preventing costly calculation errors during complex woodworking or tailoring projects.

Pro Tip from Our Technicians

To maintain the ±0.5% measurement accuracy of the DUKA ATuMan Q2, always ensure the rolling wheel is free of dust and debris before use. Our Sham Shui Po hardware specialists recommend gliding the ruler at a steady, moderate pace rather than swiping it too quickly across a surface, as this ensures the internal optical sensor captures every millimeter perfectly. Also, please note that DUKA and ATuMan are brands from the same company, so your package may feature either logo!
