Topcon GM-50 Series total stations – advanced design with superior technology
Versatile, Economical Solution
The GM-50 Series is smaller, lighter, with increased storage capacity. Offered at an even more cost-efficient option than previous models, it provides your customers the perfect tool for entry-level site layout and surveying.
The GM-50 Series was designed from the ground up to deliver the very latest technological advantages, all in a small, sleek design – you’ll appreciate the advantages from the very first measurement. Featuring a class leading EDM unit, the GM-50 is able to measure up to 4,000 m at 1.5 mm + 2 ppm accuracy, to standard prisms, and can measure in reflectorless mode up to 500 m at an incredible 2 mm + 2 ppm accuracy. Measurements are captured faster than ever, and with a beam width of 13 mm (at 30 m), the bright red laser dot pinpoints features with ease
Fast and Powerful Reflectorless EDM
Fast and accurate pinpointing with phase shift technology.
Fast distance measurement of 0.9s regardless of object.
Minimum reflectorless measuring distance – just 30cm.
Improved collimation with super-bright pointer.
Smaller EDM beam spot size for minimal distance measuring error.
Dependable measuring even at shallow incidence angles.
Ensures accurate reflective sheet distance measurement.
Tested for toughness
We perform the tough environmental tests to ensure longterm operation even under the rough site environments. GM Series total stations are thoroughly inspected with dust-proof and water-proof test chambers.
In addition, the various tests against vibration, drop, temperature, and humidity were successfully passed to achieve the best environmental spec. The measuring distance accuracy test on base line and the instrument leveling and angle accuracy test and adjustment by collimator system ensure your satisfaction on GM Series product quality.
Bluetooth® Communication
With integrated Bluetooth® capability and internal antenna, the sleek design enables you to deliver measurements cable-free to your data controller.
