Rotational seismometer METR-03

The METR-03 three-component rotational seismometer has the unparalleled sensitivity for its size, low power consumption and price. This makes it possible to use it in various areas including seismic monitoring of high-rise buildings, bridges, industrial structures, vibrational control of industrial and scientific equipment, etc.

The instrument is manufactured in a case well-suited for field installations. Reliable and easy to use, it can be set up at any angle to the horizon.

A typical cold-start time is no more than 15 minutes. 

METR-03 can be manufactured in a sealed waterproof case.
