Product Description

Product Description

Product Brief Introduction

A professional device using eye-safe lasers for continuous monitoring of building stability. It features laser mm-level deformation monitoring accuracy, acousto-optic and voice alarms, and multi-point real-time monitoring.Suitable for detecting any slight movement of dangerous buildings and other structures in scenarios like fires, earthquakes, explosions, building collapses, and landslides.

Application Scenarios

Application Scenarios

Earthquake Rescue Site: After an earthquake, the structure of buildings is severely damaged, and secondary collapses may occur at any time. The Dual Laser Structural Movement Telemeter can be quickly deployed around dangerous buildings to monitor the displacement of key parts in real time. Based on the monitoring data, rescue workers can accurately judge the stability of the buildings and carry out rescue operations safely and efficiently, avoiding casualties caused by the sudden collapse of the buildings.

Functional Characteristics

Features

Precise Monitoring: Equipped with 2 laser beams, monitoring 2 points simultaneously to enhance accuracy and coverage.

High-Precision Monitoring: High resolution with mm-level laser monitoring, 0.1° tilt resolution, and automatic precision adjustment.

Convenient Display: Built-in screen supports dual-display, making it easier to compare monitoring points, take photos, and record videos.

Safety Assurance: Features acousto-optic and voice alarms, with voice prompts for issues like too close/far distance, observation anomalies, and low battery.

Reverse Search: One-key search function for easy device locating.

Multi-Level Settings: Stepless multi-level adjustment, supporting fixed alarm values and arbitrary custom settings.
