How accurate is the laser measuring instrument?

Laser rangefinders are mainly used in underground coal mines to measure length, width, height, area, volume and places where it is difficult to measure indirectly through the Pythagorean law. Mine laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. The laser rangefinder emits a very thin laser beam to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target. The laser rangefinder is light in weight, small in size, simple in operation, fast and accurate, and is mainly used in underground roadway measurement, terrain measurement, mine construction measurement, engineering construction measurement: measurement accuracy: ±2.0mm (typical accuracy, standard deviation ).

I would like to introduce to you an accurate laser measuring instrument, which is a combination of laser measurement and physical ruler with a mobile phone APP; with convenient, accurate measurement, convenient measurement, and high work efficiency; tools that automatically generate CAD, PDF, and 3D design drawings:
