In response to the efficient positioning requirements of large-scale projects, Changzhou Kowa Electronics has launched an upgraded leveling instrument detector DDKD100. This product is equipped with a digital LCD screen for the first time, which can display laser deviation values in real time and support four precision modes: fine, medium, coarse, and extremely coarse. The highest precision is up to 2mm@40m The technical team has improved the capture speed of rotating laser lines and extended the working distance to 300 meters through multi-sensor fusion algorithms. The DDKD100 is also equipped with high-strength magnets and a rubber casing, balancing portability and durability. In terms of power management, two AA batteries combined with a 30 minute automatic shutdown function extend the battery life to 120 hours. The test data shows that it can still operate stably in a low temperature environment of -10 ℃. At present, the model has opened customized services, supporting customers to adjust the appearance label as needed.
