Product Introduction
±2.0mm accuracy per 1km double-run leveling; magnetic damping compensator stabilizes line of sight quickly even in high-vibration sites for consistent precision.
24x magnification, 32mm objective aperture, erect image with 1°25′ field of view; 4″ resolution for clear long-distance readings, good visibility in strong sunlight.
Ultra-short 20cm minimum focus (from objective lens), ideal for confined spaces, trenches and indoor surveys
360° horizontal circle with clampless endless fine adjustment; direct 1°/1gon readings for fast angle measurement, dust-proof cover for durability.
IPX6 dust & water resistance (withstands strong water jets/heavy rain); operates from -20℃ to +50℃, prevents internal condensation for all-weather reliability.
Lightweight (approx. 1.7kg) compact design for one-hand operation; standard hard case for easy transport & setup in the field
