Digital Seismometer CME-4311ND

CME-4311ND is a digital 3-component low-noise broadband seismometer. A bandwidth of up to 60 sec provides recording the most remote teleseismic occasions. With its reasonable price, the seismometer can be used for most applications as an optimal solution for a 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, light weight, rugged case, easiness in operation and low power consumption.
