| Series NETH203 Electronic Theodolite |
The detection system in the NETH 203 uses an incremental encoder to measure horizontal and vertical angles. The unique double-sided keypad allows
for quick and easy readouts, displayed brilliantly on LCD windows.
The powerful 30X telescope optics produces a crystal clear and bright image. An optical plummet,
standard on the NETH 203, allows for fast and accurate setup. |
