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 double sided LCD windows. Accuracy is 10-second.
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.
Northwest Instrument NETH203 Features:
• Converts degrees and percentage grades
• Measures both horizontal and vertical angles
• Convenient horizontal-0 slope function
• Double-sided illuminated display panels
• Dust and water resistant
• Alkaline or Rechargeable battery pack selectable
