CME-4311ND

Description

CME-4311ND is a digital 3-component low-noise broadband seismometer. A bandwidth of up to 60 sec provides a recording of the most remote teleseismic occasions.
At its reasonable price, the seismometer can be used for most applications as an optimal solution on the price/quality ratio.

CME-4311ND is excellent not only for permanent installations but also for field seismological surveys through the model’s integrated digital recording system, compact size, lightweight, rugged housing, easiness of operation, and low power consumption.
