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.
