High Precision 2 Accuracy Total Stations

High Precision 2 Accuracy Total Stations

A high precision 2” accuracy total station is widely used in modern surveying and building construction. It is an electronic theodolite integrated with an electronic distance measurement to read slope distances from the instrument to a particular point, and an computer to collect data and perform advanced coordinate based calculations.

3.Dual-axis Compensation

The ZTS-320R is configured with advanced dual-axis compensator for auto error elimination and auto accuracy compensation.

4.Absolute Encoding

The absolute encoding disk ensures high accuracy, efficiency and stable performance. No need to initialize but to measure the angle immediately as the ZTS-320R is turned on. The previous data and setting are automatically saved. No data or setting is missed even though the ZTS-320R is power-off unexpectedly.

5.High-performance MCU

Based on ARM Cortex™-M processor, the SMT32 MCU enabling the ZTS-320R extra high processing speed and low-power consumption.


The Bluetooth wireless technology makes ZTS-320R accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the ZTS-320R.

7.Data Storage

Diversified data transfer options such as SD card and Micro-USB port, which can work perfectly with our complimentary dual port USB disk.

8.Diagonal Eyepiece

Support diagonal eyepiece for observations at steep line of sight.

9.Calibration Software

Real-time diagnosis can be run with HI-TARGET Calibration software, to find out the problem quickly to ensure trouble-free operation.

10.New Data Transfer Software

The newly easy-to-use data transfer software supports different type of output data format, which can be used in AutoCAD or other brands’ post processing software.
