New Topcon ¡§Multi-Pulse¡¨ Total Station Series

Total Station GPT-3100 Series with a new, advanced technology laser for non-prism distance measurement. The GPT-3100N Series offers a major leap forward in Non-prism measurement performance in a construction site surveying Total Station.

The GPT-3100N Series will replace the GPT-3000N Series. Four models of different angle accuracy specification are available, 2¡¨, 3¡¨, 5¡¨ and 7¡¨, all but the 7¡¨ model having a dual axis compensator.

Improved Specifications

The new ¡§Multi-pulse¡¨ laser system uses multiple pulsed laser beams emitted at a constant frequency, to measure distance. It offers increased measurement performance with pin-point measurement beam, extended range, improved accuracy and lower power consumption.

  • Non-prism distance measurement range of 350 meters
  • Non-prism distance accuracy +/- 3mm +2 ppm
  • Laser Class 1M (Safe laser with narrow beam)
  • On board battery (BT-52QA) operating time 5 Hours.

Applications

The features and software of Topcon¡¦s GPT-3100 Series provide ultimate flexibility in many field applications such as:

  • Topographic Surveys
  • City Elevation Work
  • Forestry Survey
  • Quarry Surveys
  • Mining surveys
