Our take on the AtuMan Digital Electronic Measuring Ruler

The AtuMan is a disc-shaped rolling measure: you run its small wheel along a surface and a 1.8-inch LCD shows the distance. It weighs 35g, fits in a pocket, and charges over USB-C from a 200mAh battery with a long standby claim. It reads up to 9.99m per measurement and accumulates up to 99.99m at about 0.5% accuracy. It suits people measuring curves, fabric or awkward shapes where a tape sags or slips; a tape measure is still simpler for long straight runs and needs no charging.

Pros
  • Rolling wheel follows curves a tape cannot
  • Compact 35g aluminum body with a 1.8-inch backlit LCD
  • USB-C charging with a claimed 200-day standby
  • Accumulates repeated measurements up to 99.99m
  • Buzzer can be switched off
Cons
  • No laser or infrared, so it is contact-only
  • 0.5% accuracy is looser than a good tape
  • Single measurement caps at 9.99m
  • Wheel can slip on very rough or soft surfaces
  • Small screen and three-button operation take getting used to

Questions and answers

How accurate is it compared with a tape measure?
AtuMan rates it at about 0.5% accuracy, so expect small drift over long runs. A steel tape is more precise for straight distances; the wheel's advantage is curves and uneven surfaces.
How far can it measure?
A single pass reads up to 9.99 meters. Repeated passes add up to a cumulative maximum of 99.99 meters.
Does it need batteries?
No. It has a built-in 200mAh lithium battery charged over USB-C, with a claimed standby of up to 200 days.
Does it have a laser?
No. It is a contact roller only, with no laser or infrared measuring.
What comes in the box?
The electronic ruler and a USB-C charging cable.
Can it measure fabric and curved edges?
Yes, that is its main strength. The wheel rolls along curves and soft material where a rigid tape bends or slips.
Where is the AtuMan Digital Electronic Measuring Ruler cheapest?
At Deal.ai, for $29.99, as of our latest check.
