Products the products, using wavelength 635nm laser diode (laser wavelength of 50nm under), laser head clear and bright. This product can produce two or more laser under the fan and a pair of dotted lines. Laser projected on the wall fan, produces a horizontal line and one or more vertical lines (known as ink). The angle between the two or more vertical lines are 90 degrees, base node is the zenith of the instrument. This product is widely used in construction, decoration and equipment installation and other areas. Both the original levels, Theodolites, dash functions. Precise alignment of it with the laser lines will work projects 5M ± 1mm on object, make the construction process easier, less time-consuming, more easily, but also high precision guarantee construction quality.
