ATuMan LS5 40M Laser Rangefinder Distance Meter – 18 Functions, Touch OLED Display & ±2mm Accuracy

The ATuMan LS5 40M Laser Rangefinder is a compact digital distance-measuring tool designed for home improvement, interior design, construction, furniture measurement, DIY projects and everyday measuring tasks.

The LS5 combines a 0.03–40m laser measurement range, approximately ±2mm accuracy under general conditions, a 1.3-inch full-touch OLED display and multiple built-in calculation functions. ATuMan’s own product information describes the LS5 as supporting 18 practical measurement functions, making it much more versatile than a conventional measuring tape.

Its slim 95 × 26.5 × 13mm body weighs only about 38g, while the rechargeable 280mAh battery can provide approximately 4,000 measurements under specified laboratory conditions. USB Type-C charging further improves portability.

Common Problems with Traditional Measuring Tools

Traditional measuring tapes can become inconvenient when measuring larger spaces or difficult angles.

Common challenges include:

• Measuring long distances manually
• Requiring two people for certain measurements
• Difficulty measuring room dimensions accurately
• Manually calculating area and volume
• Measuring heights or inaccessible points
• Carrying bulky measuring equipment
• Difficulty reading measurements in low light
• Repeating measurements because of manual calculation errors

The ATuMan LS5 Laser Rangefinder combines distance measurement and calculation functions in a pocket-sized device.

Smart Solution for Fast Digital Measurement

The LS5 uses a laser emitter and receiver to calculate the distance between the device and a target surface.

Simply aim the laser at a suitable target and initiate measurement. The result is displayed digitally on the OLED screen.

For more advanced tasks, the LS5 can calculate measurements such as area, volume, Pythagorean distances, angles and horizontal levels, reducing the need for separate calculations or additional measuring tools.

Key Features

1. Up to 40M Laser Measurement Range

The ATuMan LS5 supports a laser measurement range of approximately 0.03–40 meters.

This makes it suitable for measuring rooms, walls, furniture, doors, windows and other objects where a conventional short measuring tape may be inconvenient.

2. ±2mm Measurement Accuracy

Under general specified conditions, the LS5 provides approximately ±2mm measurement accuracy.

The manufacturer documentation also notes that measurement performance can be affected by target reflectivity, strong background lighting, temperature and other environmental conditions.

3. 1.3-Inch Full-Touch OLED Display

One of the LS5’s standout features is its 1.3-inch full-touch OLED display.

Instead of relying on numerous physical buttons, the interface supports touch interaction and swipe gestures. ATuMan describes the design as a simplified interface using directional swipes and touch controls.

The OLED screen provides a clear way to view measurement results and operating information.

4. 18 Practical Measurement Functions

The LS5 is designed to handle more than simple distance measurement.

Depending on the selected mode, functions include:

• Single distance measurement
• Continuous measurement
• Area calculation
• Volume calculation
• Pythagorean measurement
• Secondary Pythagorean measurement
• Angle measurement
• Height measurement
• Horizontal/level measurement
• Front reference
• Rear reference
• Unit conversion
• Data calibration
• Minimum/maximum measurement
• Other integrated calculation and measurement functions

ATuMan specifically promotes the LS5 as an 18-function laser rangefinder.

5. 0.2-Second Fast Measurement Feedback

The LS5 is designed to provide measurement feedback in approximately 0.2 seconds, allowing users to quickly read the measured result after targeting a surface.

6. Continuous Measurement Mode

Continuous measurement allows the user to move the laser around a space while monitoring changing distance values.

This can be useful when identifying the maximum or minimum distance between the device and target surfaces.

7. Area & Volume Calculation

The LS5 can calculate area and volume after measuring the necessary dimensions.

For example, you can measure:

Length × Width = Area

and:

Length × Width × Height = Volume

The built-in calculation system reduces the need to manually calculate these values using a separate calculator.

8. Pythagorean Measurement

The LS5 supports primary and secondary Pythagorean measurement functions.

These functions can help calculate distances that are difficult to measure directly, such as certain heights or diagonal distances.

This can be particularly useful in home renovation, interior design and construction-related measurement tasks.

9. Angle & Level Measurement

The LS5 can also be used for angle and horizontal-level measurements.

Its angle function can display the inclination of the device, while the level function provides visual feedback to help determine whether a surface is level. Calibration may be required before using these functions.

10. Front & Rear Reference Modes

The device supports different measurement reference positions.

This allows users to account for the position of the rangefinder itself when measuring spaces such as room frames and larger structures.

The front and rear reference functions are especially useful for more precise room-dimension measurements.

11. Rechargeable 280mAh Battery

The LS5 uses a built-in 280mAh rechargeable battery.

ATuMan’s product information states that a full charge can provide approximately 4,000 measurements under specified laboratory conditions. Actual usage can vary depending on measurement distance, screen use and environmental conditions.

12. USB Type-C Charging

The device features a Type-C charging port and uses a DC 5V, below 2A charging specification.

This makes it convenient to recharge using a compatible USB power source.

13. Ultra-Compact 38g Design

The LS5 measures approximately 95 × 26.5 × 13mm and weighs around 38g.

Its slim design makes it easy to carry in a pocket, tool bag, backpack or work pouch.

14. Aluminum Alloy & Tempered Glass Construction

The LS5 is listed with an aluminum-alloy body and tempered-glass display surface.

The body uses a combination of polished and matte surface finishing, giving the rangefinder a compact and premium-looking appearance.

15. Class 2 Laser

The LS5 uses a 620–670nm laser with less than 1mW output and Class 2 classification according to the available technical specifications.

Always avoid deliberately looking into the laser beam and follow the product’s safety instructions.

16. Multiple Measurement Units

The LS5 supports common measurement units including:

• Meters (m)
• Inches (in)
• Feet (ft)

This makes it suitable for users working with metric or imperial measurements.

Its touch OLED interface, rechargeable battery and lightweight construction make it particularly convenient for professionals and DIY users who need to take measurements frequently.

ATuMan states that the LS5 was developed as its full-touch laser rangefinder and launched through Xiaomi crowdfunding in 2020. Today, ATuMan identifies itself as a standalone global tool brand, while DUKA is its China brand name.

ATuMan LS5 vs Traditional Measuring Tape

*Accuracy depends on target surface and environmental conditions.

How to Use ATuMan LS5

Step 1: Charge the Device

Before first use, charge the LS5 using its Type-C charging port and a compatible 5V USB power source.

Step 2: Power On

Activate the rangefinder and use the touch OLED interface to select the required measurement function.

Step 3: Select the Measurement Mode

Choose single distance measurement for straightforward measurements or select continuous, area, volume, Pythagorean, angle or other available modes for more advanced tasks.

Step 4: Aim at the Target

Point the laser toward a suitable solid target surface.

Avoid blocking the laser-emitting and receiving lenses.

Step 5: Keep the Device Steady

Hold the LS5 steadily during measurement.

Movement or shaking can affect measurement accuracy and may prevent a reading from being captured.
