GVM-10 Seismograph
£195.00 – £3,850.00 per week
Description
The Accudata GVM-10 is a data-logging seismograph
Accudata is delighted to introduce the GVM-10 seismograph which has been designed to monitor with absolute precision, ground-borne vibration arising during Civil Engineering Works and for Blast Monitoring air over-pressure too.
Immediately after manufacture, Accudata seismographs are sent for calibration at the European laboratory that holds ILAC accreditation to the ISO/IEC 17025 Norm. It is the first company in the world and so far the only one to have earned the highest level of accreditation for seismographs’ velocity transducer calibration.
A blast monitoring seismograph for use in the UK must be able to measure Peak Particle Velocity (PPV) in mm/s-1 from 4Hz up to 100Hz. The frequency response should be as linear as possible in each of the three axis. The air over-pressure microphone must also be able to accurately measure unweighted levels from 100dBLinear peak to 148dBLinear peak with frequencies from 2Hz to 250Hz.
The Accudata GVM-10 has a rugged construction and is manufactured to very high-quality standards in both build and in terms of accuracy. It is also very easy to use and the price is surprisingly competitive when compared to other seismographs available in the UK.
Please see the information below for the full specification for the GVM-10. We also have a User Guide and Information sheet which may be downloaded. This Seismograph is available for hire or for sale. Please contact us for pricing details or use the button below for hire.
