HTS-221L6 dual axis Total Station
System Features
Dual-axis Compensation
The HTS-22lL6 is configured with advanced dual-axis compensatorfor auto error elimination and auto accuracy compensation.  

Absolute Encoding
The absolute encoding disk ensures high accuracy, efficiency and stable performance. Initialization is needless but to measure the angle immediately as the HTS-2201L6 is turned on. The azimuth information won't be missed even the HTS-221L6 is power-off unexpectedly.       

High-performance MCU SMT32
The STM32 MCU based on ARM Cortex™-M processor enables the HTS-220/R has extra high processing speed and low-power consumption.

Bluetooth
The Bluetooth wireless technology makes HTS-221L6 accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the HTS-220/R.

Data Storage
Diversified data transfer options such as SD card, USB pen drive, mini-B interface.

Backlight
The display and keyboard with backlight for working in the dark.

Diagonal Eyepiece
Support diagonal eyepiece for observations at steep line of sight.

Calibration Software
The proprietary HI-TARGET Calibration software is accessible for real-time diagnosis to ensure trouble-free operation.  

Data Transfer Software
The proprietary HI-TARGET data transfer software supports different type of output data format, which can be used in AutoCAD or other brands' post processing software.
