continuous wave laser module / solid-state / multiple-wavelength / semiconductor
The Laser Distance Meter uses a measuring unit of WDM 3-12. The laser is secure and the blink reflex of the eye can block further damage. This laser has a wave length of 635 nm, and its power is usually up to 1 mW. It is dust-proof and well-protected from water jet out from any distance. Its protection class is IP IP 651.The length of Laser Distance Meter is 31 mm, with an error of measurement of +/-1 mm. The device comes with 2 batteries that can reach up to 5000 measurements of battery life.
