Topcon GPT 3502 LNW 2 Second Reflectorless Total Station 710167131
Overview for the Topcon GPT 3502 LNW 2 Second Reflectorless Total Station
The Topcon GPT 3502 LNW Reflectorless Total Station with 2 arc second accuracy enables measuring distances up to 6,560 feet without a prism. By incorporating Topcon's advanced time-of-flight pulse technology, this surveying equipment uses an algorithm that filters signal noise to provide high precision measurements, even on dark and wet surfaces. This total station has a laser pointer for quick indoor measurements and guide lights that provide the rod man with direction to approximately find the horizontal line.
With built-in Bluetooth, the GPT-3500 LNW series easily connects to a Topcon handheld field controller, such as the FC-5000, FC-236, FC-2600, Tesla and more. Transferring data is also convenient with the integrated RS-232C Hirose connector and 24,000-point internal memory. This reflectorless total station features TopField and Road onboard software that greatly enhances efficiency in topo data collection, construction layout, and stakeout applications.
The Topcon GPT-3502 has LCD screens on both sides, allowing construction professionals to read the display or press the required keys without having to turn the instrument. For quick inputting of point numbers, codes, attributes, and other necessary data, it features a 24-key alphanumeric keyboard with four-function keys. This Topcon reflectorless total station is protected against dust and heavy rain, and works up to nine hours using the included rechargeable battery. It comes with a 2-year manufacturer's warranty.
