China Suppliers Factory - Sokkia IM52 Total Station for Accurate Surveying and Site Layout, Reflectorless & Prism Modes
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 with Keyboard
Clear, easy-to-read display from either side of the instrument, with backlighting 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.
Precision & EDM Power
Trusted 2-inch angle accuracy for high-stakes layout and control work. Reflectorless range up to 500m, prism range up to 4,000m.
Bluetooth-Enabled
Internal antenna for cable-free connection to your controller. Allows wireless communication between the instrument and an external field controller (like the FC-6000 or Mesa 3).
Built-in Laser Plummet
Speeds up setup and ensures accurate alignment over control points.
Dual Display
Allows the single operator to read measurements from either face of the instrument. Extremely helpful during different directions (especially 180° backsights).
Built Tough
Weather-sealed IP66 housing resists dust, rain, and jobsite abuse, ensuring performance in harsh environments.
Measurement Ranges & Performance
Reflectorless Range (up to 500 meters):
- This means the iM-52 can measure distances without using a prism — just by pointing the laser directly at a solid surface (like a wall, pole, or structure).
- Extremely useful for shooting hard-to-reach targets, like: Building corners, Utility poles, Elevation marks, Inside foundations or pipe inverts.
- Limitations: You must aim at a surface with decent reflectivity. It won’t shoot 500m to a tree, brush, or water. Bright sunlight and dark surfaces reduce the effective range.
Optional Prism Range (up to 4,000 meters):
- When paired with a standard survey prism, the laser can measure much longer distances — up to 4,000 meters (2.5 miles).
- This is useful on: Long utility runs, Pipeline layout, Open land surveys, Construction control points across large sites.
Why? Prisms are highly reflective and bounce the signal cleanly back to the EDM, which boosts accuracy and distance.
