Digital acquisition Dymas 24 Master-V

Digital acquisition Dymas 24 Master-V multi-channel seismic acquisition for short and long-term monitoring of civil, industrial and monumental works.

DYMAS24 MASTER-V is a 6-channel acquisition system configurable for event or continuous recordings with all the necessary functionalities to manage single dynamic sensors or complex networks in seismic, microseismic, dynamic monitoring for permanent or temporary installations in dams, buildings or seismic stations.
The acquirer can be supplied with the accessories already pre-wired, inside a single wall or base cabinet.
