Electric Tribrach

Integrating high-precision sensors and intelligent algorithms, allowing for automatic leveling with just a simple touch to ensure the need for tedious manual adjustments and significantly lowering the operational threshold.

0.3mm/km

0.3mm/km is the fundamental guarantee for ensuring the overall precision of the control network at projects such as highways, railways, large-scale hydraulic engineering, and settlement monitoring.

Wide-angle camera

Quickly locating and locking onto the scale position at a broad field of view can eliminate the hassle of repeatedly moving the instrument to find the target and significantly reduce observation time.

Ultra-long Measuring Range

Through the collaborative innovation of optics, electronics, and algorithms, the measurement range has been extended to 200 meters, bringing previously inaccessible targets within the scope of precise and efficient measurement.

Telescope

With 43X magnification and a 50mm effective aperture, it delivers clear and reliable imaging.

Electric bubble

Transitioning from physical bubble leveling to precise electronic readings unaffected by light, line-of-sight, or viewing angles, the system provides real-time monitoring of instrument status by reducing measurement errors.

Practical Configuration

Wide range of compensation on auto leveling

3.5-inch color touchscreen with high resolution 320*480

Huge internal memory at 2GB

Multiple types of measuring modes such as line measurement,intemmediate leveling point measurement and stakeout etc

Leveling adjustment, visual axis correction are supported

Multiple types of communication such as Type-C, Bluetooth, RS-232, USB
