Seismometer CME-4311-WP10

The СМЕ-4211-WP10/СМЕ-4311-WP10 are off-shore versions of the СМЕ-4211/СМЕ-4311 broadband seismometers. 

The seismometers are supplied with waterproof cases made of strong plastic and a stainless steel bottom that allow their underwater installations down to 10 meters without a waterproof sphere. The heavy stainless bottom ensures the certain orientation of the sensor at the ocean bottom. The seismometers are very rugged and can be used both on an ocean bottom and on land.
