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.
