Laser plumb instrument is the use of optical collimation principle, the collimation axis coincides with the visible laser produced a plumb line to align the reference point to determine location of equipment, commonly used for controlling up to vote axis measurement tools. In the construction and installation of high-rise buildings, towers, chimneys, elevator, large institutional equipment and other occasions has been widely applied. In my past experience in construction is the case, but if a big circle to die, you'd better take the machine over time professionals corrected it. (Best not to adjust the minimum circle or circle) when there is a layer of vertical lines can not put a stamp ... ■ integrated body, monochrome laser high brightness, stable performance ■ automatic laser under point Delay off ■ with removable filter, the human eye can telescope ■ semiconductor lasers, small size, light weight, range finder, optical rangefinder machine vibration resistance, long life ■ The instrument features a dial so that the measurement and more accurate after calibration ■ installed zone plate, at the destination can produce red crosshairs, more accurate measurement, convenient laser vertical collimator made laser rangefinder LDM-70 for CEM independent design, development and manufacturing of industrial grade remote hand-held laser rangefinder rangefinder works, simple and safe to use, only a single person to operate without the aid of other tools, even in very demanding measurement environments can easily deal with. 70 meters to meet the needs of more industrial and construction industry. An area of ??volume calculation function; 2, using the Pythagorean theorem indirect measurement; 3, addition and subtraction functions; 4, continuous measurement function; 5, the maximum and minimum distance tracking; 6, backlit display with multi-line display; 7, beep Tip; 8, accuracy ± 1.5mm; 9, the appearance of small, double-injection skid soft feel super comfortable.
