China Sokkia IM52 Total Station - Precision Robotic Surveying Equipment from Trusted Suppliers and Factory
Precision-built for working professionals, the Topcon iM-52 (branded under Sokkia) brings rock-solid reliability and cutting-edge performance to layout and survey crews who need sharp results without overspending.
This is not some budget starter kit — it’s a full-power, ruggedized total station engineered for jobsite abuse and pinpoint accuracy, all in one streamlined package.
With 2-inch angle accuracy, long-range EDM, and an onboard software suite that makes field data collection smooth and intuitive, the iM-52 delivers real-world efficiency with zero fluff. Reflectorless shots up to 500 meters, prism shots up to 4,000 meters, and built-in Bluetooth with internal antenna let you work wirelessly and efficiently — no cables, no clutter.
Built to last in the dirt, heat, and rain, the iM-52 is IP66 rated, backed by Topcon’s global service network, and designed to get the job done right — whether you're staking corners, laying pipe, or building infrastructure from the ground up.
Sokkia IM-52 1023563-02 Key Features
30x Magnification & Red Coaxial Laser
Spot distant targets with ease, even in bright sunlight or tricky terrain. The red laser EDM beam delivers fast, precise results at the push of a button.
±6° Dual-Axis Tilt Compensation
Automatically adjusts for minor leveling errors to maintain angular accuracy — especially helpful on uneven or sloped job sites.
SDRbasic Onboard Software
Out-of-the-box functionality for Layout, topo, and basic coordinate geometry are built right in, so you can get to work without extra software or learning curves.
Dual-Face Graphic LCD & Keyboard
Clear, easy-to-read display from either side of the instrument, with backlit alphanumeric keyboard for early starts and late finishes.
Massive Data Storage
Save up to 50,000 points internally with additional support for USB flash drives — perfect for long days or multi-phase projects.
14-Hour Battery Life
The rechargeable lithium-ion battery powers full-day shifts without a problem, cutting down on field interruptions.
2-inch Angle Accuracy
Trusted precision for high-stakes layout and control work.
Bluetooth-Enabled Connection
Internal antenna for cable-free connection to your controller.
- Allows wireless communication between the instrument and an external field controller.
- Connects wirelessly to compatible field controllers like the FC-6000 or Mesa 3.
Built-in Laser Plummet & Dual Display
Speeds setup and ensures accurate alignment. Dual display allows a single operator to read measurements from either face of the instrument.
- Helpful when sighting in different directions (especially 180° backsights) without moving around the instrument.
Reflectorless Range (up to 500m)
Measure distances without using a prism — just by pointing the laser directly at a solid surface (like a wall, pole, or structure).
- Useful for: Building corners, utility poles, elevation marks, inside foundations, or pipe inverts.
- Limitations: Requires a surface with decent reflectivity. Dark surfaces, bright sunlight, trees, or water will reduce range.
Optional Prism Range (up to 4,000m)
When paired with a standard survey prism, the laser can measure much longer distances — up to 4,000 meters (2.5 miles).
- Useful for: Long utility runs, pipeline layout, open land surveys, and construction control points across large sites.
- Why? Prisms are highly reflective and bounce the signal cleanly back to the EDM, boosting accuracy and distance.
