Seismometer CME-6011-BH150

3-component low-noise broadband borehole seismometer СМЕ-6011-ВН150 is designed to be installed in dry or flooded boreholes for a long term.

The СМЕ-6011-ВН150 model has an analog output and requires connecting to an analog-to-digital data logger (not included into a standard delivery set).

The instrument does not require any settings or adjustment for operations, does not require mass centering or levelling to the vertical. It operates perfectly at angles of up to 15°.

The IP 68 means total protection against dust and water. The instrument is capable to operate in flooded boreholes at depths of up to 250 meters.
