Geophones and seismometers are measuring equipment with highly sensitive sensors that measure vibrations and earthquake signals. The safety of large buildings and the integrity of people depends on the accurate and timely measurement of such signals.
This makes it even more important for seismic sensors to undergo regular and valid traceable calibration. Calibrating a seismometer means determining its transmission properties, such as the frequency response, with high precision.
Put your trust in SPEKTRA LABS for accredited calibration of your geophones or seismometers.

Geophones are primarily used in applications involving vibrations in the construction industry. This ranges from civil engineering, such as earth excavation and the construction of excavation pit enclosures, to road construction involving compaction work, and even blasting vibrations in tunnel boring.
- Frequency range: 0.5 Hz…80 Hz or 0.5 Hz…320 Hz
(frequency range depends on the application of the geophones) - Lower frequencies can be provided upon request
- Conformity testing in accordance with DIN 45669-1 "Measurement of vibration emissions – Part 1: Vibration meters – Requirements and tests"
Applications of geophones and seismometers
"Reliability" is arguably the most important factor in all applications of highly sensitive seismometers and geophones — from monitoring and early warning to rescue operations. This makes it all the more important that everyone can rely on them to function precisely as intended.
Seismic
recordings
Highly sensitive seismometers are used to monitor seismic activity worldwide that could, in the worst case, lead to earthquakes or tsunamis.
Vibrations
On large construction sites, such as those for tunnels or dams, heavy equipment generates significant vibrations that could damage nearby infrastructure. These vibrations must be recorded for assessment purposes.
Blasting
When extracting mineral resources or intentionally altering the landscape for construction projects, blasting operations must comply with specifications that can be verified using geophones positioned in the area.
Disaster management
Geophones are used as part of seismic location systems to detect signs of life from people buried under rubble that are no longer audible to the human ear.
