Back to Basics
1. What is a Laser Distance Meter
Laser distance meter is an device using laser beam to determine distance to an object.
2. How does a laser distance meter work?
The user aims a red laser dot given out by the laser distance meter at an object, such as a wall, pole, cabinet or board. Once trigger the unit to measure, the measured distance to the red dot is displayed on the screen within 0.5 second. Precision optics and laser physics are used to quickly and accurately determine the distance to the object.
Our laser distance meters adopt the phase shift method. The measuring range can reach up to 200m with the accuracy within +/- 1.5mm.
3. What are the advantages of a laser distance meter?
Laser devices measure the true, straight line distance between two points, without the bend or sag that commonly occurs in tape measures.
b) Time savings:
It is normally much faster to turn the laser on, hold it against a wall, for example, aim at the opposite wall and press the button than to extend a tape measure to the far wall take the reading, and retract the tape. This is true in small rooms, and even more so on larger areas. The more crowded the area being measured, whether with furniture, equipment, trees, etc, the greater the time savings. Typical measuring jobs can be completed in about 1/3 the time required to use a tape measure. Time savings increase as the distances get longer.
There is significant risk involved when using a tape measure at extreme heights or on steep inclines. And, many times more than one person is required for such measurements. Now, with our LEM models new indirect measurement capabilities combined with the 90 degree tilt sensor, measurements can be taken from the ground and by a single person.
d) One Person Can Take Most Measurements:
Tape measures often require a 2nd person to hold the end of the tape. Lasers are simply aimed at a target, such as a wall, pole, door, stake or post.
e) Prevention of Errors:
It is much easier to read the digital display on a laser measuring device, which can be held in a convenient position, than to read a tape measure that needs to be held in the measuring position. Most laser devices allow the user to select the units of measure, eliminating the need for conversion of units, a common source of measurement error. Laser devices display the measured value, preventing the user from misreading the dash marks on a tape.
f) Data Interface:
Some lasers are capable of sending the measurements directly to a computer for further processing. The HERSCH LEM 50, 100, 150 and 200 models will transmit measured dimensions to any IOS or Android smart phone using a Bluetooth data interface and our free of charge software "Space Master".
