Topcon GPT-3107N Multi-Pulse Total Station : 0843 308 2507

The GPT-3100N Series replaced 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.

Multi-Pulse Laser
The “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.

Topcon’s GPT-3100 uses a dual laser optics system, one narrow beam for non-prism functions, and a broader beam when using a prism. This stabilizes the beam over long distances providing accurate measurement, even in adverse atmospheric conditions such as heat shimmer.

Dual Optical Design
Reflectorless measuring requires a finely focused beam for pinpoint accuracy. Prisms need a wider pattern to prevent off-center measuring degradation. Topcon’s dual-optical system gives you both for the maximum measuring accuracy all the time.

Precise Pulse Laser Reflectorless
Topcon’s pulse-laser “ time-of-flight” system eliminates measuring errors caused by the overlapping signals used in phase measuring systems. Accurately measuring corners or through objects such as a chainlink fence is always fast and reliable.

Longest Reflectorless Range
The GPT-3000 has the longest reflectorless range in its class! (350m) Measures up to 3000m with a prism. The dual optical design allows you the extended range using a class 1 laser- safe for all conditions, making it ideal for use in high-traffic and other heavily populated areas.

The features and software of the GPT-3100N series combine to provide ultimate flexibility in many field applications.
