Carlson CRT
The Carlson CRT is a highly accurate, fast Android-based robotic total station available in 1” and 2” versions. Its gearless Tdrive motor delivers 180°/sec rotation with class-leading quiet operation, while the EDM measures to 1 mm + 1 ppm on a prism, up to 6000 m with a single prism and 1000 m reflectorless.
The Carlson CRT is a top-of-the-line robotic total station built for surveyors who demand speed and precision. Its Tdrive motorization rotates at 180°/sec, among the fastest in its class, and does so with some of the lowest noise levels in the category. Because Tdrive uses no gears, movement is frictionless, durability is greater, and maintenance is reduced, and the very high-speed motor keeps pace even when tracking a prism mounted on a moving vehicle.
Detailed engineering delivers exceptional performance: 1 mm + 1 ppm accuracy with a prism at measurement speeds well under one second, up to 6000 m to a single prism, and up to 1000 m reflectorless (800 m for the 2” model) with millimeter accuracy. Available in 1” and 2” angle-accuracy versions, both models are noted for their smooth, quiet prism searches and rotations.
Running Android on a two-sided 6” color touchscreen, the CRT’s onboard software lets users browse online and work through a familiar touch interface. In hybrid mode with Carlson SurvPC field software, it adds a GPS Search routine, measurement to a prism on a tilted pole, and other advanced hybrid functionality.
