Northwest Instrument, Inc. Electronic Theodolite

NETH 10/20

Northwest  Instrument is proud to introduce a high quality electronic theodolite at a very affordable price. Horizontal and vertical angles are instantly displayed in digital form on a double-sided keypad. Operation is so simple, anyone familiar with job site layout can operate it.

The detection in the NETH 10/20 uses an incremental encoder to measure horizontal and vertical angles. The unique double-sided keypad allows for quick and wasy readouts, displayed brilliantly on LCD windows. The powerful 30x telescope optics produces a crystal clear and bright image. An optical plummet, standard on the NETH10/20 allows for fast and accurate setup.
