feet to meters

A laser distance meter is a device used for the precise measurement of distances, areas and volumes. It performs the same tasks as old-fashioned measuring tape, only much more quickly, accurately and without the involvement of more than one person, so laser distance meters tend to replace measuring tapes in situations where multiple measurements are commonplace.Laser distance meters send a narrow laser beam towards a target and measure the time taken for the pulse to be reflected back to the sensor. The distance is calculated when the time is divided by the speed of light. Because the speed of light is involved, laser distance meters are not suitable for sub-millimeter distances due to the large errors involved. However, measurements up to several hundred feet are very precise.The two most common applications are measuring wall-to-wall distances and finding the height between floors and ceilings. For measurements between walls, the laser distance meter is placed on one of the walls and aimed towards the opposite wall. Floor-to-ceiling measurements are usually made by laying the device on its rear end and pointing it towards the ceiling. Stability is an important factor for the measurements to be accurate.The diversity of users who benefit from the services of laser distance meters is big. Civil engineers, surveyors, insurance agents and home realtors are some of the more frequent users. Considerable money is saved during measurement operations when taking into account that measurements take seconds to perform and only one worker needs to carry them out - not two or a whole team.A laser distance meter, in order to be competitive on the market, should have certain basic features as a bare minimum.The measuring range should be sizable. On the big end of the scale it should exceed the limit of tape measures, preferably by several multipliers.Laser distance meters should have a large liquid crystal display that can show at least four measurements at the same time and should be capable of remembering the last few measurements. These two capabilities save time by exempting the user from the task of having to take out pencil and notepad. The display should also be illuminated so that readings can be done in dark conditions.They should also be compact and capable of withstanding 6-foot drops. Complete protection against dust and jet water should also be guaranteed, because these are frequent conditions in construction sites and other rough environments. A rubber band around the periphery of the unit can protect it against bumping and other abuse.

Cutting edge optical engineering technology is used for the measurement of tilt and distance. Awkward linear measurements are often computed through Pythagoras functions while volumes and trapezoid areas are calculated by other advanced geometric formulas. The most advanced laser distance meter, the Leica Disto D8, combines incredibly accurate tilt and distance measuring with a seamless Bluetooth data link so that measurements can be transferred into pocket PCs, desktops and tablets where processing by Excel, Word or AutoCAD can take place.  For more info visit feet to meters
