Prismless Total Station
Product Details
Angle Measurements
The electronic theodolite part of prismless total station is used for measuring vertical and horizontal angle. For measurement of horizontal angles any convenient direction may be taken as reference direction. For vertical angle measurement vertical upward (zenith) direction is taken as reference direction. The accuracy of angle measurement varies from 2 to 6 seconds.
Distance Measurements
Electronic distance measuring (EDM) instrument is a major part of total station. Its range varies from 2.8 km to 4.2 km. The accuracy of measurement varies from 5 mm to 10 mm per km measurement. They are used with automatic target recognizer. The distance measured is always sloping distance from instrument to the object.
Coordinates Measurements:
Advantages
The following are some of the major advantages of using total station over the conventional surveying instruments:
Field work is carried out very fast.
Accuracy of measurement is high.
Manual errors involved in reading and recording are eliminated.
Calculation of coordinates is very fast and accurate. Even corrections for temperature and pressure are automatically made.
Computers can be employed for map making and plotting contour and cross-sections. Contour intervals and scales can be changed in no time.
