HOTO SW-HT30 Laser Distance Meter 30M – Digital Rangefinder with OLED Display, Bluetooth & Mi Home App

The HOTO SW-HT30 Laser Distance Meter 30M is a compact digital laser rangefinder designed for fast and accurate distance measurements around the home, office, workshop, construction site and DIY projects.

With a maximum measurement range of 30 meters (98 feet) and accuracy of approximately ±2mm, the SW-HT30 can quickly measure room dimensions, wall lengths, furniture spacing and other straight-line distances without requiring a traditional measuring tape. HOTO lists the device with an OLED display, Bluetooth connectivity, USB-C charging and Mi Home app synchronization.

Its small body measures approximately 73 × 33.2 × 16.8mm and weighs around 36g, making it easy to carry in a pocket, toolbox or work bag.

Common Problems with Traditional Measuring Tapes

Traditional measuring tapes are useful, but measuring longer distances can sometimes be inconvenient.

Common challenges include:

• Measuring alone can be difficult
• Tape can bend or move during measurement
• Longer distances require more space
• Reading small tape markings can be inconvenient
• Recording multiple measurements manually takes time
• Measuring room dimensions can require assistance
• Repeated measurements can become tedious

A laser distance meter provides a faster alternative for many straight-line measurements.

Smart Solution for Fast Digital Measurement

The HOTO SW-HT30 uses a laser beam to calculate distance and display the result digitally.

Simply point the device toward the target surface and activate the measurement. The result appears on the OLED display, allowing you to measure without manually extending and reading a traditional tape.

The device can also connect to the Mi Home app through Bluetooth, allowing supported measurement data to be stored and used for floor-planning and documentation.

Key Features
