Longer Range And More Stable Precision

HTS-521L10 has a new optical structure design. It adopts a new ranging algorithm and cooperates with high-quality electronic and optical components. The reflectorless range is up to 1000m with 3+2ppm accuracy. The prism mode range is farther than 6000m with 2+2ppm accuracy.

Colorful Display

2.8-inch and 240*320 pixels high-brightness color display is still clearly visible under the strong sunlight. The rubber keys have a backlight display, which makes operation clear in dark environment.

Trigger Key And Auto Senor

1. The data can be acquired by trigger key with one click, which improves the speed and accuracy of the measurement greatly.
2. Get temperature and pressure automatically.


HTS-521L10 is widely applied to control surveys, construction, mining, tunnel, railway, highway and other application scenarios. HTS-521L10 was born for efficiency.
