Laser distance meter

What is a laser distance meter?

Laser distance meters quickly and precisely measure distances between two points. The start point of the measurement is the set measurement edge of the laser distance meter and the second point is the end point of the beam. The maximum range varies depending on the device and can extend to over 100 m. Digital distance measurement offers many advantages over conventional measuring using a folding rule or measuring tape. Distances can be measured precisely and conveniently in just a few seconds. In addition, depending on the model, the devices can calculate areas and volumes of spaces at the touch of a button, function using a touchscreen and have integrated Bluetooth and camera functionalities and an integrated tilt sensor.

How does a laser distance meter work?

The laser focuses on a target for measurement. The distance meter then emits a laser pulse, which begins the measuring process. The pulse is reflected from the target and received by the photocell in the device. This enables the exact distance to be calculated using the time span between the emission and reflection of the laser. In practice, SOLA uses a process in which the phase change between external pulsing and internal reference pulsing is determined. Only a small surface area is necessary for location when using laser measurement. For ultrasound, it must be much larger in order to enable it to reflect relevant sound waves. Laser distance meters are easier to use and more accurate than ultrasound distance meters, and far more convenient than measuring using a folding rule and measuring tape.

What measuring functions do laser distance meters have?

Laser distance meter functions vary depending on the manufacturer and device. Conventional devices simply measure distances and show these on the display but if the user also wants to calculate areas and volumes and determine inaccessible distances or heights via angle measurements, then they should think about purchasing a more complex device. Laser distance meters that have these functionalities are equipped with an integrated tilt sensor. In these times of greater interconnectivity, many laser distance meters also now come equipped with a Bluetooth interface. Together with the app, lengths can be sketched and dimensioned directly on the smartphone, for example, or measurement results can be saved, managed and shared.

LENGTH MEASUREMENT

Determines a simple distance from the set measurement edge of the laser distance meter.

SURFACE MEASUREMENT

Automatically calculates an area by measuring length and width.

VOLUME MEASUREMENT

Calculates the volume of a space by measuring length, width and height.

MIN. / MAX. MEASUREMENT

Determines the minimum or maximum distance by measuring the shortest distance between two points or the greatest distance, e.g. along the diagonal dimension.

CONTINUOUS MEASUREMENT

Rapidly determines a required target distance using continuous measurement.

INDIRECT 3-POINT MEASUREMENT

Determines an inaccessible distance via three length measurements. A measurement is then derived using a 90° angle.

INDIRECT 2-POINT MEASUREMENT

Determines an inaccessible distance via two length measurements. A measurement is then derived using a 90° angle.

INDIRECT MEASUREMENT VIA ANGLE

Measures an indirect and inaccessible height by means of two length measurements. Thanks to the automatic electronic tilt sensor, an additional 90° angle measurement is not required.

INDIRECT DISTANCE MEASUREMENT

Determines an indirect distance without needing to get to the start and end points. From one position, two length measurements are made to the respective measuring points.

AUTOMATIC DISTANCE MEASUREMENT

Length measurement is used on an elevated target point; its corresponding height and distance are then calculated automatically using the tilt sensor.

ADDITION/SUBTRACTION

Adds and subtracts measurements quickly and simply.

MEASUREMENT MEMORY

The memory function allows to store and retrieve measuring results.

INCLINATION SENSOR

Calculates indirect distances or heights using the angle measured by the electronic inclination sensor.

Where can laser distance meters be used?

There are a whole range of possible uses for laser distance meters. Laser distance meters are primarily used in the construction industry: be it in construction works, renovations, interior design or in exterior works, laser distance meters are needed everywhere. In a matter of seconds, you can calculate distances, areas and volumes of indoor spaces or check measurements and distances. A wide range of occupations use distance meters, ranging from drywall builders, painters, tilers and floorers, joiners and kitchen fitters to carpenters, bricklayers or even architects and interior decorators.

What are the advantages of a laser distance meter?

Laser distance meters simplify the measuring process, save time and are convenient to use when working. Different measuring functions are available to you right away at the push of a button. Distances can be measured and checked and areas and volumes can be calculated in a matter of seconds, all with exceptionally high accuracy, which is far superior to those calculated by measuring tape or folding rule. A further advantage of laser distance meters is that precise measurements can be made alone, without requiring the help of another person. Laser distance meters also simplify measurements in difficult situations, i.e., ‘overhead’ measurements.

How precise is a laser distance meter?

The measuring accuracy of laser distance meters varies depending on the device and manufacturer and can usually be found in the technical information or in the operating manual. Often, laser distance meters have a measuring accuracy with a tolerance of +/- 2 mm. This measuring tolerance usually refers to a given distance and increases with greater distances. The majority of SOLA laser distance meters have a measuring tolerance of a maximum of +/- 1.5 mm for distances up to 10 m. The specified measuring accuracy relates to normal measuring conditions. Under unfavourable conditions, e.g., direct sunlight, non-reflective surfaces or measurements on glass or shiny surfaces, may cause an increase in inaccuracy and lead to measuring errors.

What range do laser distance meters have?

As with the measuring accuracy, the maximum distance of laser distance meters varies greatly. Laser distance meters that are used in the construction industry usually cover measurement distances of 20–60 m.
