Topcon Europe Positioning is pleased to announce the release of a Total Station 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
GPT-3100N

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
