Sokkia iM-52 PSBL 2-inch Intelligent Measurement Total Station - Dual Display w/ Bluetooth & Laser Plummet (US Version)

The Sokkia iM-52 PSBL 2-inch Total Station (SKU: 1023563-02) is engineered for contractors and surveyors who need accurate, repeatable measurements on demanding jobsites. Delivering 2" (2-arc-second) angular accuracy, this intelligent measurement system combines a rugged IP66-rated body with dual displays, built-in Bluetooth, and a laser plummet — giving your crew the tools to work faster and smarter from layout through final inspection.

Jobsite-Ready Performance

Whether you're setting control points on a civil construction project, laying out structural columns, or performing as-built verification, the iM-52 PSBL is built to keep up. The instrument's onboard programs handle common tasks like distance measurement, coordinate layout, REM (Remote Elevation Measurement), and area calculation without needing an external controller. Pair it wirelessly with your data collector or field tablet via Bluetooth and eliminate cable clutter on busy sites.

• Long Battery Life: Full-day operation on a single charge keeps production moving

Job Applications

Structural Layout: Set column centerlines, anchor bolt patterns, and slab edges with 2" angular precision — keeping your structural steel and concrete work on spec from the start.

Civil Site Work: Establish horizontal and vertical control, stake road alignments, and check grade on earthwork operations with reliable distance and angle data direct to your field software.

As-Built Verification: Confirm installed elements match design coordinates before concrete is poured or finishes go in, catching costly errors early with reflectorless EDM measurement.

Utility & Underground Layout: Use REM and coordinate programs to locate manhole centers, pipe inverts, and utility crossings accurately — even when direct measurement access is limited.

Frequently Asked Questions

What does the '2-inch' specification mean on the Sokkia iM-52 PSBL?

The 2-inch (2") rating refers to the instrument's angular accuracy — it can measure horizontal and vertical angles to within 2 arc-seconds. This level of precision is well-suited for commercial construction layout, boundary surveying, and civil site control work where tight tolerances matter.

Does the iM-52 PSBL require a prism to measure distances?

No. The iM-52 PSBL includes a reflectorless EDM that can measure distances to surfaces like walls, facades, and inaccessible targets without a prism. For longer-range or higher-accuracy distance work, a prism is recommended and supported up to 5,000 m.

What software is compatible with the Sokkia iM-52 PSBL?

The iM-52 PSBL communicates via Bluetooth and is compatible with popular field data collection software including Sokkia's own field apps, as well as widely used platforms that support standard total station communication protocols. Contact Express Tools for current compatibility guidance.

Is the iM-52 PSBL covered under a warranty when purchased through Express Tools?

Yes. As an authorized Sokkia dealer, Express Tools sells the iM-52 PSBL with the full manufacturer's warranty. Contact our team for specific warranty terms and service support options.
