Broadband seismometer CME-4311-WP10
The СМЕ-4311-WP10 model is low-noise broadband ocean-bottom seismometer for installations at depths of up to 10 meters.
The seismometer is supplied with a waterproof case made of strong plastic and a stainless steel bottom which allow underwater installations at depths of up to 10 meters without a waterproof sphere.
The heavy stainless bottom ensures the certain orientation of the sensor on the ocean bottom.
