A laser distance measure is an instrument that can accurately measure the distance of the target by using a parameter of the modulated laser. A pulse laser rangefinder is to shoot a beam or a series of short pulse laser beams to the target when working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the laser beam to the reception and calculates the distance from the rangefinder to the target.

The application of hand-held laser distance meter in house measurement has always been a concern and painstaking work of the housing management department. It is not only directly facing the people, but also directly related to the economic interests of the people. Therefore, the control of the error of house measurement is particularly important. According to the past practice, the use of a tape or steel tape to measure the building area, the use of area measurement, although it can also meet the basic requirements, but in long-distance measurement, There is a large error in the measurement of the height of the measuring layer and the difficult to reach the ground, and there are shortcomings such as heavy labor intensity and complicated work. In today’s era of rapid development of high-tech, such primitive and traditional measurement methods have obviously not met the requirements of rapid and efficient information society. For this reason, after the introduction of hand-held laser distance finders, after several months of practical use, it is generally believed that this instrument is particularly suitable for the measurement of buildings with complex structures, middle and high buildings and long distance buildings. Easy to use, accurate measurement data (3mm accuracy), improved work efficiency (non-contact measurement), completely abandoned the method of measuring houses with a tape (or steel tape), reduced the survey error, ensured the area measurement accuracy, and the measurement results made the owner more convinced.
