Description
The AL28M series automatic levels are designed for a variety of elevation control and alignment tasks including general building construction, cut and fill measurements, area leveling, and landscaping.
Reliable automatic compensators ensure stability and accuracy in the line of sight. Telescope optics are bright and clear providing sharp images for ease of viewing. A short focusing distance provides for better performance in tight spots or on steep slopes. Stadia lines on the reticle make distance calculations easy. A horizontal scale directly below the eyepiece makes angle measurement quick and convenient.
The GL412N is a single grade laser that also offers long-range operation in addition to its grade capability of -10 to +15 percent. An RC402N full-function remote control offers an easy to use menu-driven interface. The radio remote operates at a range up to 330 feet (100 meters) and provides the ability to make grade changes and start automatic alignments remotely, which can significantly reduce setup time.
