Laser distance measures offer a fast and convenient solution to distance measuring applications that would otherwise require multiple steps to achieve. The Hilti PD-I Laser Meter is engineered to make tape measuring methods obsolete and provide unmatched productivity and sophistication for a full range of measuring applications. The PD-I Laser Meter provides a distance operating range of up to 262' for long distance capacity, and has a top-class accuracy of +/- 1/16" for maximum precision. For added versatility, it provides both standard and metric units of measurement, and the following measurement functions: Distance; Area; Volume; Permanent; Min/Max; Add/Subtract; Stake-Out; Pythagoras (2 point); Pythagoras (3 point); Pythagoras (partial height). Convenience features include an auto power-off function that shuts off the device automatically for increased run time performance, and a simplified user interface button and screen.
