MR3003C
The MR3003C in Syscom’s rugged RED BOX is a compact vibration/motion measurement system. As such it meets all user expectations in a state-of-the-art device and thus is a highly reliable and efficient tool for many applications. The MR3003C is suitable for structural monitoring (DIN 4150-3, SN 640312 and others) and human comfort (DIN 4150-2, ISO 2631 and others).
Product supplied by Syscom Instruments.
Overview
Due to its design and reliability, the MR3003C is an efficient vibration solution for different temporary and fixed measurements in the civil engineering and strong-motion surveys.
Applications include:
- Civil Engineering and Human comfort: Industrial Vibrations – Construction Site Monitoring – Tunneling
– Truck and Rail Traffic – Blasting Monitoring – Model Verification - Earthquake Engineering: Building Monitoring – Monitoring of Structures (Dams, Bridges..).
- Geology: Soil Characterization.
- Earth Science: Earthquake Monitoring (seismic Intensity). Continuous data stream in MiniSeed/SeedLink format.

Speak with an Expert
I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
