Description

CME-4311-WP10 is an analog, 3-component, low-noise broadband seismometer. It’s the off-shore version of the CME-4311 broadband seismometer. These seismometers are supplied with waterproof cases made of strong plastic and a stainless steel bottom that allow their underwater installation up to 10 meters depth without a waterproof sphere. The heavy stainless bottom ensures a certain orientation of the sensor at the ocean bottom. These units are very rugged and can be used both on an ocean bottom or on land.
