Yato Laser Distance Meter 50 m is a compact distance meter optimized for indoor measurements. The measurement range is 0.05–50 m, and the typical measurement accuracy is ±2 mm. The extended functionality covers single and continuous measurement, min/max distance monitoring, and switching between measurement units (m, ft, in, ft+in).
The device calculates area and volume from directly measured values. Indirect measurements are performed in several modes based on the Pythagorean theorem, allowing distances to be determined even when there is no direct line of sight to the object. The choice of measurement basis (3 starting points) makes it easier to set a reference for room and furniture measurements.
Built-in continuous tilt angle measurement (digital electronic “spirit level”) helps to estimate angles and slopes during measurement. Backlit LCD improves readability in low light. Memory stores the last 99 measurements, and automatic power off (laser ~30 s, device ~180 s) saves batteries.
The laser is class 2 (650 nm, <1 mW, red dot). The device is operated in a temperature range of 0–40 °C and is powered by two AAA batteries (1.5 V or 1.2 V). The design is designed for daily indoor measurements where speed and a simple user interface are key.
Intended use:
Indoor room, space and line measurements: Quickly measure distances, wall lengths and room heights. Area and volume calculations reduce the need for manual calculations and speed up, for example, the estimation of material consumption.
Placements and installations: Positioning of furniture, rails and devices and confirmation of reference distances. Continuous measurement and min/max modes make it easy to “find” the correct distance.
Indirect measurements and inclinations: Pythagoras functions allow the determination of heights/distances when direct alignment is not possible. The inclination angle display supports the work of installers and surveyors.
Documentation and repeatability: The memory of 99 measurements helps to transfer measurements later to drawings or systems and reduces errors.

Yato Laser Rangefinder 50 m – user manual:
Start and align: Set the measuring base (front/back of the device). Aim the laser at the target and hold the device steady.
Single measurement: Press the measurement button once; the result is saved on the display and, if desired, in memory.
Continuous measurement / min–max: Activate continuous mode; move the device and follow the minimum and maximum values to find the correct measurement.
Area and volume calculation: Enter consecutive dimensions (length × width × height); the device will calculate the values automatically.
Pythagoras modes: Select the appropriate indirect measurement mode and follow the on-screen instructions; take measurements in sequence from a stable position.
Tilt angle: Follow the angle view during installation or measurement.
Calibration: Use the calibration offset (?9…+9 mm) to fine-tune the measurement base if necessary.
Power saving: The laser turns off in ~30 seconds and the device in ~180 seconds without use.
Warnings:
Laser class 2: Do not look directly into the beam or aim it at people/animals; avoid reflections from shiny surfaces.
Use only indoors or in situations where the dot is clearly visible; bright sunlight will reduce visibility.
Keep the device dry and clean; avoid shocks.
Batteries: install correctly; do not short-circuit or expose to fire.
Keep out of reach of children.
Frequently Asked Questions, FAQ:
Can the device be used outdoors? Yes, but the dot is usually not visible in bright sunlight; measurement is better in dim light or shade.
What do Pythagoras functions mean? They allow for indirect height/distance calculation from multiple measurement points when direct alignment is not possible.
How many measurements can be stored in memory? Up to 99 of the most recent measurements, which can be reviewed later.
What does an accuracy of ±2 mm mean in practice? In typical indoor measurements, the error is approximately ±2 mm when the measurement is made according to the instructions from a stable position.
Recycling instructions:
Batteries: Please dispose of used batteries separately.
Packaging: Cardboard/paper - cardboard collection; plastic bags and covers - plastic collection.
Device at end of life: Dispose of as waste electrical and electronic equipment (WEEE).
