Electronic Total Station (ETS)
Electronic Total Station The Total Stations are recent and most common types of electronic surveying instruments comprising of mainly an EDM, an EDT and a limited capability micro processor in a single compact and mobile unit which can be setup on tripod at field during survey to collect essential distance - direction data to define the positions of points with respect to each other.
What Is Total Station • COMBINATION OF EDT + EDM + Computer • ON BOARD MEMORY SYSTEM INCLUDING DOWNLOAD & UPLOAD FACILITY • IN BUILT PROGRAMME FOR CO-ORDINATE CALCULATION, AREA CALCULATION, STAKE-OUT etc.
Principal Features Of ETS • • Measures Direction & Distance Simultaneously Effortless Levelling Through Electronic Digital Bubble Effortless Centering Through Laser Plummet Automatic Correction For Temperature, Pressure, Curvature and Refraction Multi Axis Compensator Data Storage Facility Data Downloading and Uploading Facility On Board Computer
Principal Features • Effortless Levelling Through Electronic Digital Bubble • Automatic Correction For i) Temperature ii) Pressure iii) Curvature
WATER AND DUST RESISTANT The rain cannot come into the inside of the instrument in unexpected rainfall and it is specially designed for the bad site conditions the machine is completely dustproof
LUMI GUIDE OPERATION
REFLECTORLESS MEASUREMENT REMOTE CONTROL SYSTEM WITH THIS FEATURE YOU CAN DETERMINE POINTS AND MEASURE DISTANCES WITHOUT USEING ANY REFLECTOR.
TRI-AXIAL COMPENSATOR Tri axis compensator performs fine leveling and error which occurs where the vertical and horizontal axis intersect
AUTOMATIC ATMOSPHERE SENSOR The built in automatic atmospheric sensors, measures the temperature and pressure in real time, and initiates ppm correction. thus, the user no longer needs to bother with inputting these data
LASER PLUMMET The machine enables easy to center over a setup point thanks to the laser plummet. The intensity of the laser point can be adjusted step-by-step to maintain visibility even in critical lighting conditions
