In today's world, manufacturers strive to keep up with the times and constantly develop 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 who are engaged in construction, the laser ruler occupies a special place. It was invented relatively recently, but it is steadily increasing the staff of its admirers.
What is a laser ruler? This is a special electronic device used to measure various distances. Its principle of operation is to reflect 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 measurement accuracy, 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 and area. Laser rulercan store up to 10 measurements.
Field of application of laser lines
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 are not needed to use it.
Pros
- The laser ruler measures distances up to 70 m. Experts say that if necessary, this figure can be increased by 30-40%.
- Instrument error 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.
- Fast – results are visible instantly.
- The ability to work with the device to one person, without assistants.
- You can not only measure distances, but also make instant calculations.
Cons
- Errors when measuring small distances.
- Using a tripod is recommended for longer distances.
- The main disadvantage that a laser ruler has is the price, which is much higher than mechanical devices for measuring distances.
Useful tips for using laser lines
If you want to measure a distance over 10 m, it is advisable to use a target to increase the measurement accuracy. The target can be any small object, such as a box of matches. In thatIn this case, the beam will be reflected from a certain target and the measurements will be especially accurate.
Summing up, it must be said that the laser ruler, which is also called a laser tape measure or a laser rangefinder, successfully replaces traditional tape measures in many areas of production and business. Also, this device is increasingly purchased for personal use. The laser rangefinder is able to calculate volume and area, perform subtraction and addition, which usually have 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 measure and calculate impenetrable segments, using various versions of the Pythagorean theorem about indirect measurements.
