SARA seismometer

DoReMi seismograph

The DoReMi seismometer is an innovative device that adopts a distributed architecture along cables and integrates all electronic components required for seismic signal recording.
This architecture has several advantages and overall makes the system very convenient to use under any operating conditions.

application
This device is mainly designed for MASW surface wave exploration and is suitable for various seismic exploration methods, including:
Refractive wave survey
• Reflection wave survey
• Tomography imaging
HVSR spectral ratio method
ESAC/SPAC 􀀁 and 􀀁 ReMi methods
• Water survey
• Landslide investigation
• Underground/cross hole measurement

VelBox high-performance seismometer

VELBOX is a compact fully integrated high-resolution seismometer. Based on the SL06 recorder core that has been verified on site, it is equipped with a three-axis seismometer, forming an efficient on-site monitoring device that can be quickly deployed. It can be put into operation in just a few seconds after startup, supporting the integration of various seismic monitoring components ranging from low-cost 4.5Hz detectors to high-resolution 0.1Hz sensors
The device can also be equipped with MEMS accelerometers, and this special version is called the Velbox hybrid. The hybrid version can capture weak signals through seismometers and fully record vibration data through MEMS accelerometers (with a range of 2g) during strong vibrations, making it suitable for all types of earthquake monitoring scenarios.
Adopting a sturdy aluminum alloy shell that has undergone anti-corrosion spraying treatment, it can be deployed in the field for a long time without the need for complex protection.
Its weight and structural design can ensure good ground coupling effect.
Flexible data connection methods support direct connection between devices and central observation stations.

application
*Aftershock research
*Soil property assessment (Nakamura, HVSR)
*Reservoir microseismic monitoring
*Operational Modal Analysis (OMA)
*Structural Health Monitoring (SHM)
*Earthquake Early Warning System (EEWS)

SL06 24/32-bit seismograph

The SL06 24/32-bit seismometer is a high-resolution recorder based on the Linux operating system, supporting standard flash drive operation. The device provides a variety of Internet services, including the SeedLink protocol, FTP client and server functions, and can transmit data to mainstream central station recording software (such as SeismoWin, EarthWorm, SeisLog, SeiscomP, etc.) in real time. Since its launch in 2006, this model has become the main equipment in the field of dynamic monitoring. After undergoing V1 and V2 versions and continuous optimization, two new versions are now launched: the V3 version equipped with an upgraded collector, and the rack mounted version designed specifically for indoor installation.
Application field
*Earthquake Early Warning System/Network
*Station level seismology
*Reservoir microseismic monitoring
*Planetary Seismology and Geophysics
*Operational Modal Analysis (OMA)
*Structural Health Monitoring (SHM)
*Large scale tomographic imaging, used for earthquakes or microseismicity

SR04 Collector EDUGEO Version

SR04 collector provides EDUGEO version. This is a high-performance instrument, but mainly designed for individual users and non professional organizations.
The instrument can record earthquakes at home and publish the records to the Internet.
When used in conjunction with PC and SEISMOWN software suite, you will have a fully functional earthquake monitoring station. The system can be equipped with built-in sensors or you can use your own sensors.

Teaching Application
This instrument can be successfully used in schools and training. Low cost and small size enable people to familiarize themselves with earthquake records. Professors can use it for physics lectures in the classroom, covering various physical laws from resonant motion to structural analysis.
