A total station — reflectorless electronic surveying instrument with 2"–5" angular accuracy and integrated EDM for construction set-out and land surveys. Multi Trade Combines stocks and demonstrates in Guwahati for the Northeast; price on request.
The total station has transformed field surveying from a slow, multi-instrument operation into a single-set-up process that delivers digital, coordinate-ready data. Multi Trade Combines in Guwahati supplies reflectorless total stations with angular accuracies between 2 and 5 arc-seconds, covering the full range of construction survey, land survey, topographic mapping and engineering-alignment applications across Northeast India. As a key supplier of surveying instruments in the region since 1993, we understand the diverse terrain and project types encountered across the eight NE states.
A reflectorless total station uses an infrared laser to measure distances to almost any surface — a wall, a road edge, a cliff face or an existing structure — without requiring a retroreflective prism. This is especially valuable in NE India's difficult terrain: surveyors working in landslide-prone areas of Meghalaya, in dense forest edges in Arunachal Pradesh, or on narrow riverbanks along the Brahmaputra can measure inaccessible points without putting an assistant in a dangerous position. When a prism is used, range extends to several kilometres for control traverses.
The instrument's onboard processor computes horizontal distances, elevations and coordinate differences in real time, and stores observations in internal memory for later download to office software such as AutoCAD Civil 3D, LISCAD or Total Station Manager. PWD survey divisions, irrigation department project offices, NHAI contractors, railway survey teams and private civil engineering consultancies across Assam and the Northeast all rely on total stations as their primary field survey tool.

Government PWD and BRO survey divisions use total stations on every major road and bridge project from the plains of Assam to the mountain highways of Arunachal Pradesh and Manipur. NHIDCL and NHAI contractors setting out alignments for the four-lane highway upgrade of NH-37 and NH-27 require total stations meeting MORT&H specifications. Railway survey teams preparing DPRs for the unfinished rail connections in the Northeast use 2" total stations for precise alignment work. Urban local bodies in Guwahati use total stations for road widening and drainage surveys. Private civil and structural engineering consultants in Guwahati, Shillong, Dimapur and Imphal use them for building set-out and topographic surveys. We supply and demonstrate total stations at our Guwahati counter; accessories and batteries are stocked locally for quick replacement.
A total station is always used with a levelling tripod, surveying prism (for long-range work), prism pole and field book or data collector. A reflectorless set-up adds a target card or painted surface to improve signal return in low-contrast conditions. Auto levels complement total stations for precise elevation benchmarking over short distances. Laser distance meters serve as a quick check tool on site when total-station precision is not required. Multi Trade Combines stocks tripods, prisms, prism poles and auto levels alongside our total station range.
A total station is an electronic surveying instrument that combines an electronic theodolite with an electronic distance meter (EDM) in a single unit. It measures horizontal angles, vertical angles and distances simultaneously, allowing survey crews to determine the precise coordinates of points on the ground. In construction and civil engineering, total stations are used for setting out building foundations, road alignments, bridge pier locations, boundary surveys and topographic mapping. Reflectorless models can measure distances to walls or surfaces without a prism.
For highway alignment and large-area topographic surveys, a 5" (five-second) total station is generally sufficient. For precise control surveys, deformation monitoring, tunnel alignment and bridge engineering, a 2" or 1" instrument provides tighter angular resolution. Reflectorless range up to 300–500 m suits most site set-out work. Multi Trade Combines can help you specify the right accuracy class for your project — call +91 91812 13332.
