01
For long-span bridge deflection, dam settlement and sliding, high-risk slope displacement, heritage bridges and long tunnels.
02
One device can cover multiple points for deformation-trend tracking and anomaly warning, reducing manual inspection pressure in distant or high-risk areas.
03
Can work with solar power, 4G/5G, video review, cloud monitoring platforms and on-site alarms for unattended projects.
