OVERVIEW
Description
DoReMi Seismograph is an advanced digital telemetry system engineered for modern seismic surveys, featuring recording electronics embedded directly within the cable. This innovative architecture delivers exceptional modularity, operational efficiency, and deployment flexibility, making it ideal for MASW, ReMi, refraction, reflection, and downhole seismic investigations.
Each channel operates as an independent seismograph, and when combined, the units create a seamless and easy-to-deploy acquisition network scalable from 1 to 255 channels, allowing adaptation to projects of any size or complexity.
The system incorporates a lightweight, rugged, rechargeable power system, ensuring uninterrupted field operation, while intelligent standby modes preserve battery life during idle periods. Digital conversion at the sensor level minimizes noise, crosstalk, and signal loss, guaranteeing high-quality data acquisition even in challenging environments.
Fully Compliant with ASCE 7-22 Site Classification Requirements
Recent ASCE 7-22 regulations emphasize the importance of reliable VS30 shear-wave velocity measurements for seismic site classification and structural design. The DoReMi system provides a complete turnkey solution for MASW and ReMi surveys, enabling field teams to acquire data and derive VS30 results directly on site, dramatically reducing post-processing time and project turnaround.
Recommended Configuration – 24-Channel System
For most engineering and geotechnical applications, we recommend the 24-channel configuration, which offers the optimal balance between portability, depth resolution, and acquisition efficiency for standard VS30 and shallow shear-wave velocity profiling projects.
Included Software & Training
The system is delivered as a complete operational package, including:
• Advanced acquisition and processing software
• MASW processing modules
• Data visualization and interpretation tools
• Continuous software updates and maintenance support
• On-site or online training sessions for rapid team onboarding
This ensures users can move from delivery to productive field deployment with minimal setup time.
Field-Proven Reliability
With over 15 years of successful field operation and hundreds of installations worldwide, the DoReMi Seismograph is a trusted solution among geotechnical engineers, seismic consultants, and research institutions. Designed and produced in-house, the platform ensures rapid customization, technical support, expert consultation, and long-term service reliability.
