Rotational seismometer METR-01

The METR-03/METR-01 rotational seismometers provide new measuring means and data channels in engineering geophysics, exploration seismology, rotational seismic surveys, seismic monitoring of high-rise buildings and constructions (bridges, hydroelectric dams and so on), security systems based on the seismic area control and many other applications. 

The sensors are very rugged, does not require any maintenance and well-suited for portable applications and field tests as well as for permanent installations. The one-component (METR-01) and three-component (METR-03) modifications are available.
