The Sokkia SET 5W

Being fully water-resistant, the SET5W operates dependably even where conventional total stations do not, such as in sudden showers, continuous drizzling rain, or the high humidity of underground construction sites.

Sokkia's SET5W Waterproof Total Station is ruggedly built to withstand harsh operating conditions.

Performance Features :

Proven Dual-axis Compensator

The High-performing EDM

Powerful Telescope

Outstanding Mobility

The SET5W can be easily customized to your preferred key assignments.

Missing Line Measurement (MLM)

Remote Elevation Measurement (REM)

Angle Repetition

For enhanced accuracy in the horizontal angle measurement, the SET5W can measure in repetition. It then calculates and displays the average of the multiple angle measurements.
