In today's world, manufacturers strive to keep up with the times and are constantly developing new devices and technologies designed to improve and facilitate both our daily lives and working moments. Among the devices of the new generation, useful for those involved in construction, the laser line stands in a special place. It was invented relatively recently, but is steadily increasing the staff of its admirers.
What is a laser ruler? This is a special electronic device used for measuring various distances. Its principle of operation is the reflection of a laser beam from a distant object. This reflection is generated, and the measurement result is displayed on the screen. The laser ruler is distinguished by high accuracy of measurements, as well as the ability to work both indoors and outdoors, at temperatures up to -50C! Many models not only measure distance, but also independently calculate volume, area. The laser ruler can store up to 10 measurements in memory.
Scope of laser rulers
These devices are used in construction, topographic surveys, including in military affairs, in navigation. Many people want to buy a laser ruler for home use, because special skills and knowledge for its use will not be needed.
pros
- The laser ruler measures distances up to 70 m. Experts say that, if necessary, this figure can be increased by 30-40%.
- The accuracy of the device is up to 2 mm.
- The step (unit) of measurements is 1 mm.
- Ease of use - just press two or three buttons and get an accurate measurement.
- Efficiency - results are visible instantly.
- An opportunity to work with the device to one person, without assistants.
- You can not only measure distances, but also make instant calculations.
Minuses
- Errors when measuring small distances.
- At long distances, it is advisable to use a tripod.
- The main disadvantage that the laser line has is the price, which is significantly superior to mechanical devices for measuring distances.
Useful Tips for Using Laser Rulers
If you want to measure a distance of more than 10 m, it is advisable to use a target to increase the accuracy of measurement. Any small item, such as a box of matches, can be a target. In this case, the beam will be reflected from a specific target and the measurements will be especially accurate.
Summing up, it must be said that the laser ruler, which is also called laser roulette or laser range finder, successfully replaces traditional roulettes in many areas of production and business. Also, this device is increasingly being purchased for personal use. The laser rangefinder is able to calculate volume and area, perform subtraction and addition, which usually has to be done separately, and this process is long, and the results are often incorrect. The most advanced models are equipped with functions that help to measure and calculate impregnable segments, using different versions of the Pythagorean theorem about indirect measurements.
