Laser rangefinder is an instrument that uses laser to measure the distance of target accurately. Laser rangefinder emits a very fine laser beam to the target when it works, and receives the reflected laser beam from the target by photoelectric elements. The timer measures the time of laser beam from launching to receiving, and calculates the distance from the observer to the target. Laser rangefinder is light in weight, small in volume, simple in operation, fast and accurate, and its error is...
The measuring range of laser rangefinder is from several meters to several kilometers. Users should choose it flexibly according to specific conditions.
