The Dymas 24 V Master is a multichannel portable seismic recorder for long term monitoring with stable configuration inside dams and structures.
Dymas 24 Seismic Recorder is used for both Microseismic & Vibrational studies.
The multichannel acquisition system allows upto 6 channels in a single compact metallic cabinet provided for fixing on wall or floor. It is equipped with an LCD display & keyboard membrane for status update & command function.
The system is configurable from 8 GB internal memory to 64 GB for long term monitoring.
The management software DYMASOFT, integrated with VIBROSOFT data processing software allows to build up efficient dynamic monitoring networks.
