Descriptions: This Professional Distance Meter employs laser technology to measure distance, area and volume accurately, quickly and conveniently. It has a wide measuring range 60m (196ft)andparticularly high accuracy 2mm.In addition, this meter can make use of Pythagorean Theoremto measure distances or lengths indirectlywhen direct measurement is not feasible. This meter also has various functions including continuous measurement,addition/subtraction functionand Max/Min measurement. Other main features are including 100 data memories,switchable units (metre, inch &feet) &backlight LCD with multi-line display. The bubbles level equipped can be used as a spirit level tool. Laser distance meter has a wide variety of applications in construction and industries. It is very useful and convenient to give accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, gardens, roads, infrastructures, etc. Features: Wide measuring range up to 0.05~60m High accuracy Quick measurement of distance, area and volume Automatic calculation of area and volume Indirect measurement by Pythagorean Theorem Continuous measurement Min/Max distance tracking Easy addition/subtraction of measurement Switchable among metre(m), inch (in), feet (ft) Easy targeting withbright laser pointer Large LCD with backlight Display illumination and multi-line display 100 data records Self-calibation -9mm to +9mm Bubble level equipped as a spirit level tool Auto correction and error report technology Low battery indication Auto / manual power off function
