Stability Monitor – Leader Sentry B1

Price: POA

Product Description

Leader SENTRY is a stability monitor that detects the structural movements of an unstable building. Its laser continuously monitors detected movements and displays changes for real-time awareness.

Leader SENTRY can detect a 1 mm structure movement at a distance of 50 m! A telescopic sight helps to point the laser accurately at the targeted unstable structure.

It allows firefighters and USAR teams to be alerted by a visual and audio alarm (105dB) when a structure movement, however small, is detected.
