Laser measuring - Why?
Tape Measures
Take a tape measure and measure a room. Commonly there will be furniture, tables and expensive ornaments in the way. On most occasions two people will be needed to measure over or around these obstacles. It’s quite a time consuming task. Oh yes a try not to break anything!
In order to save time, you may use an ultra-sonic tape measure. By their very nature, ultra-sonic devices are estimators and are not precision measuring instruments. If you take ten measurements of a room, you will find that 8 measurements are different.
Ultra-Sonic
Ultra-sonic devices emit a sound wave similar to ships sonar and measuring the first returning signal. If you measure a living room, the signal will bounce of furniture, tables, plants and curtains. Anything in front of the wall, will return a signal before you achieve a measurement from the wall it’s self.Ultra-sonic instruments are cheap but not accurate. You would spend more time taking a measurement than with a tape measure.
If you want speed and accuracy, a laser measuring device is the preferred choice.
Laser Measure
A small laser beam is emitted and can be accurately positioned onto the target area. When a measurement is taken, millions of light waves are sent through the laser beam. The instrument measures the time it takes to send and receive these signals. In most cases this happens in a fraction of a second.With a laser beam the small red dot can be position over or under an item. The laser will not be affected by surrounding obstacles and will only measure the distance to the dot.
This allows the operator to measure outdoors to a range of 200 meters. With advances in the Leica Disto technology, digital point finders help to position the laser even if you can not see the red dot. The best bit, only one person is required and it only takes a fraction of a second.
The best laser measuring device is the Leica Disto.
