4400mAh high capacity battery
Absolute Encoding
The absolute encoding disk ensures high accuracy, efficiency and stable performance. Initialization is needless but to measure the angle immediately as the ZTS121R is turned on. The azimuth information won’t be missed even the ZTS 121R is power-off unexpectedly.
Dual-axis Compensation
The ZTS121R is configured with advanced dual-axis compensatorfor auto error elimination and auto accuracy compensation.
T-P Sensor
Equipped with an accurate sensor of temperature and pressure. You no longer need to measure the temperature and pressure and insert the PPM values.
High-performance MCU
The STM32 MCU based on ARM Cortex™-M processor enables the ZTS121R has extra high processing speed and low-power consumption.
The Bluetooth wireless technology makes ZTS121R accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the ZTS121R.
Data Storage
Diversified data transfer options such as SD card, USB pen drive, mini-B interface.
The display and keyboard with back light 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.
