Rotational seismometer METR-13
The METR-13 three-component rotational seismometer is similar to the METR-03 seismometer, but its frequency range is optimized for seismic exploration.
The instrument is reliable and easy to use and can be set up at any angle to the horizon.
A typical cold-start time is no more than 15 minutes.
The instrument is reliable and easy to use and can be set up at any angle to the horizon.
