100m Laser Distance Meter
100m Laser Distance Meter is an distance measuring instrument that uses lasers to accurately measure the distance to a target. The Laser Rangefinder emits a laser beam to the target, and the photoelectric element receives the laser beam reflected by the target, and calculates the distance from the emitting point to the target. It can measure distance, area and volume, and can measure both indoors and outdoors.
Widely use in house decoration, building construction, real estate and DIY related, the laser measure is ideal for measuring areas or objects including rooms, apartments, buildings, factories, garage, desks, chairs, sofa, closet, floor, etc.
