Mileseey DT20 Bluetooth laser measuring tape 40m with digital display

Mileseey DT20 is an innovative 3 in 1 laser measuring tape Bluetooth, designed for professionals and home craftsmen. This smart device combines a classic 5-meter tape measure, 40-meter laser measurement and a digital display in one compact device. The DT20 model remotely sends data to a mobile phone via Bluetooth, creating ideal conditions for efficient work in construction, repair and engineering.

Laser measuring tape Bluetooth — main features

• Laser measurement up to 40 meters — using a wavelength of 630-670 nm (Class 2 laser), you can accurately measure long distances without wasting effort and time. Help for working at high altitudes.
• Digital display with instant pointer — after pulling the roulette wheel, the results appear immediately on the screen. No need to review and read confusing markings, just look at the screen.
• Bluetooth data transfer — DT20 sends measurement data to a dedicated app. You can analyze, store, and share results with your team or clients.
• Pythagorean measurement (Pythagoras) — calculates distance using the Pythagorean theorem. This allows you to measure quantities that are not directly accessible.
• Calculating areas and volumes — by entering a few measurements, the device automatically calculates the area or volume. Ideal for architects and builders.
• Rechargeable battery and heating protection — Lithium battery allows for long-term use without replacement. Operates from 0 to 40°C, protecting against damage in cold weather.
• High measurement accuracy — laser accuracy is ±3 mm, and tape measure accuracy is ±1.5 mm. This guarantees professional-level results.
