DELTA-03 DIGITAL SEISMIC SIGNAL RECORDER
The Delta Seismic Recorder is designed to detect seismic signals from external (natural and artificial) seismic vibrations. It is a permanent seismic station with the possibility of data logging to a removable high‐capacity flash disk, and data transmission to a PC for real‐time analysis and recording.

It is a permanent seismic station with the possibility of data logging to a removable high‐capacity flash disk, and data transmission to a PC for real‐time analysis and recording.
The Delta‐03 includes the Delta‐03M signal recorder, cables, a magnetic antenna, a PCMCIA Flash disk (2 …. 32GB), and a socket to connect with the seismic cable.
•4 (8) channels for easy connection to any sensor (i.e., seismometers,accelerometers)
•Low power consumption
•Embedded mode of accuracy with internal GPS
•Geophone calibration mode
•Removable mass storage
•Small size and lightweight.
•Earthquake Early Warning
PC‐based via interfaces Ethernet 10/100 and RS‐232
Performed in real time; Recorder uses the high‐stability TCXO to maintain time accuracy; Internal GPS receiver sets and calibrates real‐time clock automatically within time points specified by operator or at the command of an operator.
The recorder is designed to be part of a telemetering network using the GSM system or satellite modems in the data transfer mode or telephone modems; Telemetering networking is possible using the Internet via GPRS modems and local networks with an external IP address.
The software is designed for Windows 9x/Me/2000/XP.
