Overview for the Topcon OS 102 2 Second Reflectorless Total Station

With MAGNET Field software on board the Topcon OS-102 Total Station with 2-second accuracy, survey professionals can perform all calculations onsite without the need for a data collector. This alphanumeric and touchscreen optical instrument has a highly-accurate EDM and trigger key that enables the recording of measurements with just a press of a button. It also features an advanced angle encoder system and exclusive long-range Bluetooth technology for everyday surveying in remote locations.

Ultra-Powerful EDM and Angle Encoder

In reflectorless mode, the OS is able to measure up to 1,640 feet and approximately 16,400 feet using a standard prism with its high-end EDM beam and laser pointer. This Topcon total station is perfect for outdoor aiming with its coaxial green or red guide light and ultra-narrow EDM beam that precisely measures walls, corners and through fence openings and tree branches in only .9 seconds. 

Topcon’s exclusive Independent Angle Calibration System (IACS) enables the OS-102 to adjust its own angle measurement system. Its motion clamp and precise tangent locks keep the angle positions accurate even when you are pressing the touchscreen and keyboard. The EDM trigger key is ergonomically placed and allows you to easily get a series of measurements without taking your eye off the telescope.

For accurate leveling even on rough terrain and quick instrument setting, this total station is equipped with a dual-axis compensator and a laser plummet with 5 brightness levels.

On-board MAGNET Field Software

MAGNET Field software offers an easy to use graphical interface with large icons, enhancing the dual large color touchscreen and alphanumeric keyboard experience of the Topcon OS total station. This data collection software indicates what data is needed on each screen and allows you to view and edit points and lines with ease. With the built-in Windows CE 6.0 operating system Built-in, MAGNET Field not only provides a very productive interface, but also features many stakeout, roading, coordinate geometry (COGO) and adjustment calculations that eliminate the need for a data collector.

Long-Range Bluetooth

In case you need to use a data collector or other handheld device, the OS total station has LongLink technology that enables surveyors to operate more than 1000 feet away! Featuring Class 1 Bluetooth wireless technology, this Topcon total station offers flexibility for stakeout. Simply aim this surveying instrument and the remote rod position triggers the measurement from the data controller, eliminating the frustration of hand signals and errors on layout. 

Topcon TSshield Security System

If your OS total station is misplaced or stolen, the TSshield advanced security feature enables you to disable the device by sending a coded signal and track its location. The same module also offers daily connectivity to cloud-based Topcon servers and automatically sends on-screen alerts for available software updates.

Connectivity and Long Battery Life

The Topcon OS-102 has a large 750 MB internal memory, 8GB USB flash memory and RS-232C serial port for storing and transferring files to your PC or data collector. With up to 20-hour battery life on a single charge, this reflectorless total station along with the Topcon ES Series has one of the longest battery-lives in the industry. And with an IP-65 rating, this field instrument is dustproof and protected against water jets from any angle.

The OS-102 total station is also compatible with any of Topcon's field controllers, such as the Topcon Tesla, FC-2600, FC-250, FC-236 and FC-25.

This Topcon total station package comes with a lens cap, lens hood, stylus pen, tool kit, USB stick, carry case with straps, wiping cloth, battery, battery charger  and a 2-year manufacturer’s warranty.
