Overview for the Topcon GTS 255 5 Second Total Station

As part of Topcon’s new GTS200 series, the Topcon GTS-255 Total Station is a reliable optical instrument that works with a variety of prisms and data collectors for land surveying and construction stake-out. With 5-second accuracy, tilt sensor and optical plummet, this total station is able to record accurate distances and angles.

Accurate and Reliable

The Topcon GTS-255 features 5-second accuracy and 30x magnification, allowing surveyors to read slope and horizontal distances up to 7,500 feet with a single prism and take angle measurements to as little as 0.3 second.

This land surveying tool features an enhanced absolute encoder that can recall its last position as soon as the power is turned on. It also has a tilt sensor and dual-axis compensator for perfect leveling and an optical plummet to precisely mark the total station’s location.

Survey Software and Memory

Calculating and processing measuring points is fast and easy with the GTS-255’s built-in onboard software. This total station also stores large amounts of field data with its 24,000 points of internal memory, which can be transferred to your PC or data collector using a standard Topcon 9-pin cable.

Functionality and Features

This Topcon total station has alphanumeric keyboard and dual display that enable surveyors to input data with ease. Its environmental rating of IP-54 protects it against dust and water splashes, while the rechargeable Ni-MH battery provides up to 9 hours of continuous distance and angle measuring, or up to 40 hours measuring angles only!

Compatible with Topcon Data Collectors

For more advanced layout tasks, the GTS-255 can be used with any of Topcon's field controllers running MAGNET Field software, such as the Tesla, FC-2600, FC-250, FC-236 and FC-25.

This GTS255 total station package comes with the GTS-255 with 5-second accuracy, lens cap, tool kit with case, plastic rain cover, silicon cloth, battery, battery charger, carrying case and a 2-year manufacturer’s warranty.

Combining excellent precision and durability, the Topcon's GTS-255 total station provides surveyors a value priced measuring solution. With 2-second angular, onboard programs and plenty of data storage, this field surveying instrument is ideal for every day surveying and stakeout.
