A truly portable, broadband, weak-motion triaxial seismometer
The Güralp 3ESPC is a proven weak-motion triaxial broadband seismometer for the price and size of a medium-motion instrument.
Ideally suited for long-term temporary and permanent installations in areas with low to moderate noise levels. The instruments' broadband response and low self-noise level make it suitable for seismic monitoring at all scales: local, regional and teleseismic.
In addition to the analogue instrument, we also offer two digital variants:
3ESPC -analogue instrument
3ESPCD - integrated with a digitiser for low-power deployment with Flash memory storage
3ESPCDE - integrated with a digitiser and acquisition module with web-based user interface and communication over serial and Ethernet
