Description
The HTS-521L10 HD Color Screen Long-Range Total Station is a high-performance surveying instrument engineered to deliver exceptional precision, reliability, and ease of use in demanding field environments. Designed with a new-generation optical system, advanced EDM module, and absolute encoding technology, it ensures fast and stable measurement results for construction professionals, surveyors, engineers, and geospatial experts.
Equipped with a 2.8-inch high-visibility HD color screen, the HTS-521L10 enhances usability and improves field efficiency, allowing surveyors to work comfortably even under strong sunlight. Its redesigned optical system and sealed encoder disk significantly boost accuracy and stability, ensuring dependable performance during long working sessions.

1000m reflectorless measurement
The powerful EDM enables 1000m reflectorless measurement and up to 5000m–6000m with a single prism, all with high accuracy of 3mm + 2ppm (reflectorless) and 2mm + 2ppm (prism). With a rapid measuring time as fast as 0.3 seconds, field tasks become faster, smoother, and more efficient.
Built-in productivity tools—including stakeout, area projection, MLM, offset measurement, repeated measurement, resection, and coordinate geometry programs—make the HTS-521L10 an ideal companion for road construction, building projects, mining operations, tunnel alignment, railways, control surveys, and general engineering tasks.
For enhanced stability and precision, the instrument features a dual-axis tilt sensor, high-precision bead shafting, and an auto sensor that automatically reads temperature and pressure to optimize measurement accuracy. These hardware improvements ensure smooth performance even on rough or unstable terrain.
The HTS-521L10 supports multiple communication and data transfer methods, including USB, U-disk, RS232, Bluetooth, and popular formats like CSV, DXF, TXT, DAT, GT7, and HTF. It also integrates seamlessly with SurvCE and Hi-Survey, and supports secondary development for custom workflows.
Powered by a 3000mAh high-capacity Li-ion battery, the device offers up to 36 hours of continuous angle measurement or 18 hours of mixed-field operation, ensuring long working days without interruption. Its IP65 protection rating guarantees resistance to dust, water spray, and harsh environmental conditions.
Engineered for maximum reliability, accuracy, and user convenience, the HTS-521L10 Long-Range Total Station is the perfect choice for professionals seeking long-term durability, improved workflow efficiency, and consistent high-precision performance across all surveying disciplines.
