The instrument is based on an optical collimation principle, the use of a semiconductor laser generates telescope collimation axis coincides with the visible laser beam 2 meters feet engineering test equipment, can be directly observed by the human eye. The instrument uses integrated body, stable and reliable performance. The instrument uses a semiconductor laser, a small size, light weight, resistance to vibration engineering test-foot special equipment, long life and other advantages. Laser with high brightness, good color and other characteristics. Laser optical axis of the laser system and the telescope instrument strictly visual axis concentric with coke, coaxial, so the engineering inspection feet, when the telescope sight the target, at the destination can produce a visible red spot. Under the Instrument for points with automatic delay off feature will help to extend the life of laser tube, to save battery. By focusing on the point of the laser spot is no need to improve the measurement accuracy. Instrument equipped with a square-shaped laser target engineering test-foot package sales, user operation more convenient. According to user needs can be equipped with a zone plate, installed after the zone plate, at the destination can produce red crosshair measurement is more accurate and convenient. Instrument equipped with a removable filter, remove or install the removable filter, brightness telescope field of view is not affected, mounted on removable filter, when you turn the laser eye through a telescope . The instrument has dial so that a more accurate measurement and calibration. Instrument uses two AA alkaline batteries, two new AA-size alkaline batteries can be used continuously for 2 to 3 hours. Nanfu alkaline batteries are recommended. The compact and portable Leica DISTO D2 take ergonomic grip compact design, you can safely hold in your hand or into any pocket. Clearly show the results are displayed on three lines of the display. Instant in the dark, use lighting to display the results can still be easily read. Simple clever Minimum / maximum measurements, tracking and storage of results makes your work easier to measure from edges or corners of the use of flip-base, you can work in any measurement environment. Quick and easy touch of a button, you can measure the distance and calculate the area or volume.
