In recent years, the global construction industry has continuously increased its requirements for construction efficiency and accuracy, and the market demand for laser detectors as key positioning tools continues to rise. Manufacturers represented by Changzhou Kowa Electronics have launched multiple products that are suitable for different scenarios, such as the leveling detector (LS100/DDKD100) that supports a working distance of 1-300 meters, and the upgraded LR300 with magnetic and adhesive design. Industry data shows that the market share of green lasers (520 ± 10nm) has been increasing year by year due to their higher visibility. In addition, customized demand has become a new growth point, including the adaptation of shell color and label content to different brand logos. Experts predict that the compound annual growth rate of laser measurement and control equipment will reach 8.2% in the next five years, and intelligent and multi-sensor fusion technologies may become the focus of competition.
