Electronic Total stations

Specification:- A total station or TST (total station theodolite) is an electronic/optical instrument used in modern surveying and building construction. The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM) to read slope distances from the instrument to a particular point. A versatile all-in-one non-prism total station that mounts a Windows®CE.NetTM-based data collection function in a pulse total station that is accurate and without incorrect indication.

	Data collector function and application program are standard provisions.
	Windows®CE.NetTM is installed.
	A large color display + touch panel
	Real-time 3D view (Tuned to movements of the system, 3D positions are graphically displayed)
	Small diameter pin point pulse
	Data send and receive function using the Internet (e-mail).
	Versatile interfaces (Transmission and reception via a CF card, USB and RS-232C)
