Survey Lab

Theodolite

It is used to measure horizontal and vertical angles. It consists of a telescope mounted to swivel both horizontally and vertically.

Total station

It is useful for measuring horizontal angles, vertical angles and distance.It does this by analyzing the slope between itself and a specific point

Electronic theodolite

In modern electronic theodolites, the readout of the horizontal and vertical circles is usually done with a rotary encoder. These produce signals indicating the altitude and azimuth of the telescope which are fed to a microprocessor

LevelDumpy/quick setting

The dumpy level is an optical surveying leveling instrument consisting a telescope tube firmly secured in two collars fixed by adjusting screws to the stage by the vertical spindle. Relative elevation of different points of a surveying land is determined

Auto level

An automatic level, also known as a self-leveling level or a builder’s auto level, is a professional tool that can establish or verify points in the same horizontal plane.

Hand held G.P.S

GPS survey equipment makes it possible to obtain location, distance, and height measurements almost instantaneously.

Laser distance meter

The laser distance meter is used for accurately determining the distance of an object or span without contact by way of a laser. The basic measuring principle is based on measuring the transit time of laser pulses between the laser distance meter and the

Plane table board

A plane table is a device used in surveying site mapping, exploration mapping, coastal navigation mapping, and related disciplines to provide a solid and level surface on which to make field drawings, charts and maps.

Plane table stand

A plane table is set over a point and brought to precise horizontal level. A drawing sheet is attached to the surface and an alidade is used to sight objects of interest.

Plain Alidade

The alidade is used for determining the directions of objects and is commonly deployed in detailed survey especially plane table, mapping

Spirit level

This equipment is sensitive, and it's used to level the table by placing it in two positions at right angles of each other and setting the drawing board so the bubble is evenly centered.

Trough Compass

The trough compass is used for marking the magnetic north line on the drawing sheet of the plane table.

Plumbing fork

Plumbing fork with a plumb bob is used in large scale surveying for Centring of plane table and for Transferring of ground point.

Plumb bob

A plumb bob is a weight with a pointed tip on the bottom that's hung from a string, and it's used to establish a vertical reference (called a plumb line).

Prismatic compass

A prismatic compass is a navigation and surveying instrument which is extensively used to find out the bearing of the traversing and included angles between them, waypoints (an endpoint of the lcourse) and direction.

Surveyor's compass

surveyor's compass, is an instrument used in surveying to measure horizontal angles . A circumferentor consists of a circular brass box containing a magnetic needle, which moves freely over a brass circle, or compass divided into 360 degrees.

Levelling staff(4m) - wooden and alluminium

A level staff, also called levelling rod, is a graduated wooden or aluminium rod, used with a levelling instrument to determine the difference in height between points or heights of points above a vertical datum..

Open cross- staff

Type of cross-staff which is also used to set out 90 degree

French cross staff

Used to set out either 45° or 90°.

Steel Ranging rod 3m

A ranging rod (or range rod) is a surveying instrument used for marking the position of stations, and for sightings of those stations, as well as for ranging straight lines.

Iron arrow

Arrows in surveying are the marking pins that are mostly used in the chain surveying. They are used to mark the end of the chain length; if the length of the line to be measured is more than a chain length..

Chain metric (30m)

Metric chains are made in lengths 20m and 30m. Tallies are fixed at every five-meter length and brass rings are provided at every meter length except where tallies are attached

Engineer's Chain(100')e

A surveyor's measuring instrument consisting of 1-foot (30.48-centimeter) steel links joined together by rings, 100 feet (30.5 meters) or 50 feet (15.25 meters) long

Optical square

The optical square uses a to reflect and refract a beam or sighting 90 degrees, it is used in pairs in surveying and in a singular block in metrology.

Planimeter

A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape.

Abney clinometer

Abney clinometer is an instrument used in surveying which consists of a fixed sighting tube, a movable spirit level that is connected to a pointing arm, and a protractor scale. By using trigonometry the user of an Abney level can determine height, volume,

Hand level

A hand level is a tool used for 'rough leveling' – that is, estimation and not precision. ... The device is generally used by grading contractors and land surveyors to compare multiple points against a reference point to get approximations of level or dis

Tangent Clinometer

This is a very handy and useful instrument used mostly along with a plane table. It measures angle of elevation or depression and their tangents.

Sextant

Sextant, instrument for determining the angle between the horizon and a celestial body such as the Sun, the Moon, or a star, used in celestial navigation to determine latitude and longitude

Pentagraph

Pantograph, instrument for duplicating a motion or copying a geometric shape to a reduced or enlarged scale.

Ediograph

This Eidograph is an mechanical plotting instrument used to redraw maps at a smaller or larger scale. It has the same function as a pantograph.

Fiber / steel Measuring Tape -50m,30m 20, 10m

A tape measure or measuring tape is a flexible ruler used to measure size or distance. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool.

Digital balance

RA digital balance is used to weigh ingredients in a laboratory. When a weight is applied to the digital balance, an electronic circuit generates a current which is then converted into a digital readout on the display.
