Different Types of Surveying Instruments

Surveying equipment has been around since the times of the Egyptians, and only in recent years has the use of lasers been introduced to make the process of measuring things that much easier and simpler to achieve. There are many options available:

Laser Levels

The biggest benefit to be gained from using a self level laser over a manual device is that it can find its own level without the person having to make adjustments.

Single and Dual Grade Lasers

This kind of laser surveying equipment is used in order to measure as well as define the gradient of a slope. However the disadvantage of the single grade version is that it can only calculate what the gradient is on one particular plane whilst the dual version can do so using two different planes at once.

Rotating and Straight Line Lasers

The rotating laser produces a beam of laser light from a beacon which is able to rotate and so can produce a level plane right across 360 degrees. The straight line laser when used in surveying puts out either one or more laser beams and is able to perform the function which allows the surveyor to produce a cross or plumb line.

Pipe Lasers

This particular piece of surveying equipment is most often used when new pipes, drains or sewers are being laid (installed). Once one section of the pipe has been laid the laser will be placed inside it so the next pipe can be aligned and graded in line with the one already in place. Using this helps to ensure that the pipes being installed are done so with a great deal more accuracy.

Laser Receivers

This particular piece of equipment is often used with the laser level (which we have mentioned above) and is able to cover a much wider area of land that needs measuring. Also it enables the user to use the laser level both outside and when the sun is bright. The receiver works by being able to pick up the beam from the laser level and will adjust its height until such time as the right level has been found. As soon as this is achieved the receiver will emit a constant sound.
