Overview for the Topcon OS 105 5 Second Reflectorless Total Station

Perform all calculations onsite without using a data collector with the Topcon OS-105 Total Station with built-in MAGNET Field software. This reflectorless total station with 5-second accuracy features a powerful EDM and exclusive long-range Bluetooth technology for precise distance and angle measurements even in remote locations. With a large memory, USB port and advanced security feature, the alphanumeric and touchscreen Topcon OS allows you to easily and securely transfer field data for post-processing.

Powerful Distance Measurement

The high-end EDM beam and laser pointer of this Topcon total station measures up to 1,640 feet in reflectorless mode and up to 16,400 feet with an incredible 2mm+2ppm accuracy when using a standard prism. It features an ultra-narrow EDM beam that precisely measures walls, corners and through fence openings and tree branches in only .9 seconds. It also has coaxial green or red guide light for fast outdoor aiming and direction during stakeout.

Even when you are pressing the touchscreen and keyboard, the Topcon OS maintains accurate angle positions with its motion clamp and precise tangent locks. Dual-axis compensation ensures accurate leveling even on rough terrain and a built-in laser plummet allows for quick instrument setting with 5 brightness levels. This total station also has an EDM trigger key that is ergonomically placed to enable surveyors to record a series of measurements with just a push of a button.

MAGNET Field Software and Windows OS

The Topcon MAGNET Field software on-board the OS-105 total station provides stakeout, roading, coordinate geometry (COGO) and adjustment calculations to eliminate the need for a data collector. The shortcut buttons and fast access tabs of MAGNET Field optimize the dual large color touchscreen and alphanumeric keyboard of this field instrument. With the onboard Windows CE 6.0 operating system, this data collection software offers an easy to use graphical interface with large touch icons.

Topcon LongLink Technology

For stakeout and other field applications that require the use of a field controller, the OS total station features  exclusive LongLink Bluetooth technology that enables surveyors to operate more than 1,000 feet away from the prism pole! Simply aim this optical 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

TSshield is an advanced security feature of the OS total station, which allows the owner to disable the device by sending a coded signal and track its location if it is misplaced or stolen. 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

Save files to your PC or data collector with this total station’s 750 MB internal memory, 8GB USB flash memory and RS-232C serial port. Along with the Topcon ES Series total station, the OS-105 has one of the longest battery-lives in the industry with  20-hour operating time on a single charge. With an IP-65 rating, this field instrument is dustproof and protected against water jets from any angle.

The OS-105 total station can be used with Topcon Tesla, FC-2600, FC-250, FC-236 and FC-25 for field operations where a data collector is needed.

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.
