Calibration Service – Geophones and Seismometer

For reliable calibration of seismic sensors and measuring equipment.

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 for accredited calibration of your geophones or seismometers.

  • Reliable and traceable calibration that meets DAkkS requirements
  • Factory calibration and testing for compliance with any international and local standards upon request
  • Lowest possible measurement uncertainty
  • In addition to geophones, we also offer accredited calibration of vibration sensors and seismometers
  • Fast standard processing times in accredited laboratories

Our accreditation certificate

SPEKTRA offers the appropriate calibration service for a variety of seismometers.

Seismometer / seismic measurement chains

Calibration in accordance with ISO 16063-11:1999, ISO 16063-21:2003, DKD-R 3-1 Sheet 3: 2018 or DKD-R 3-1 Sheet 4: 2018

  • Frequency range: 0.1 Hz...400 Hz
  • Acceleration: 0.001 m/s²...20 m/s²)

 

We also have the right service for special vibration measurement technology such as geophones.

Geophones and vibration meters

Calibration in accordance with DIN 45669-1„Measurement of vibration immissions - Part 1: Vibration meters – Requirements and tests”.

The main application for geophones is measuring vibrations in the building industry. This includes underground work, such as excavation and constructing excavation shoring, road construction with compaction work, and blast vibrations in tunnel driving.

  • Frequency range: 0.5 Hz…80 Hz or 5 Hz…315 Hz
    (the frequency range depends on the application of the geophones)
  • Calibration for lower frequencies upon request

 

 

 

Fields of application

Geophones and seismometers are used to monitor structures.
Geophones or seismometer monitor building vibrations.
Rail traffic is also monitored by seismometers.
If explosions are carried out, seismometers can record the vibrations.
Vibration measurement technology makes a major contribution to safe tunnel construction.
Geophones and seismometers are used for ground surveys.
