The latest LR300 laser marking instrument detector released by Changzhou Kowa Electronics has improved the measurement accuracy to 1mm@10m (Detailed), up 50% compared to the previous generation product (LR100). This device adopts a dual display mode of LED+LCD, supporting dual prompts of sound and light, and is equipped with high-strength magnets that can quickly adhere to metal surfaces. The technical team optimized the spectral recognition algorithm to ensure precise capture of 635nm/520nm lasers, covering a working distance of 1-50 meters. In addition, the LR300 shell adopts encapsulation technology, with a drop and dust resistance level of IP54, suitable for harsh environments such as construction sites and mines. In terms of power supply, two AA batteries can support automatic shutdown for 30 minutes without operation, significantly enhancing the battery life. At present, the product has passed CE certification and is put into mass production.
