Lab Materials

Level Instrument: a device to determine height differences and ensure horizontal alignment. It consists of a telescope mounted on a tripod, with an internal leveling mechanism like a bubble vial or automatic compensator. The instrument is used alongside a leveling staff to measure vertical distances, helping in tasks such as creating level surfaces, calculating gradients, or setting out elevations.

Leveling Staff: a graduated rod used in surveying to measure vertical distances in conjunction with a leveling instrument, such as a dumpy level or auto level. It is placed vertically at a point on the ground, and the surveyor reads the staff through the level instrument's telescope to determine the elevation or height difference between points.

Plumb bob: a simple essential tool used to establish a vertical reference line. It consists of a pointed, weighted object (usually made of metal) suspended from a string or cord. When the cord is held still, the plumb bob aligns itself with gravity, providing a true vertical line.

Ranging Rod: a straight, cylindrical pole used in surveying to mark and align points on the ground. It is typically made of wood, metal, or fiberglass and is painted in alternating red and white (or black and white) bands for visibility over long distances.
