The marking distance meters use lasers with a wavelength of 650 or 635 nm, resulting in clear and bright laser lines. The instrument outputs two laser sectors; when projected onto the working surface, they generate a horizontal line and a vertical line (known as ink lines). The instrument has a wide horizontal adjustment range, eliminating the need for precise adjustments. It can rotate 360° so that the laser lines reach all directions, enabling accurate targeting of work objects. The lock button ensures the instrument is securely locked when turned off to prevent damage from vibrations. A spiral hole at the center of the lower part of the base allows the instrument to be fixed on a lifting stand, facilitating adjustment of the horizontal line height. The instrument is compact, attractive, easy to use, and reliable. It is widely applicable in indoor construction, decoration, and equipment installation project acceptance. Technical specifications:
