The eentec DR4050 ver. P is the latest version the rugged, ultra low power, high-performance, versatile 24-bit seismic recorder line.   It is designed for the most demanding requirements in high performance seismic or strong motion research. 

This state-of-the art seismic standard recorder features up to 12 external sensor inputs.  Options include an internal accelerometer, a higher dynamic range internal accelerometer with 24-bit resolution or an external 24-bit triaxial sensor input with or without an internal standard accelerometer.   Each channel has a high resolution ADC that ensures no channel to channel skew in any configuration, and a very low-power, high-performance 32 bit RISC that controls the data acquisition, real-time digitization and filtration.  The standard unit is suitable for building and structural monitoring (optional internal high-resolution accelerometer available).  The external 3-channel sensor input can be ordered with the internal accelerometer and be used with a broadband seismometer (EP or SP series), rotational seismometer (R-1), 6DOF sensor (R1-A3) or EA accelerometers

The powerful, full-featured single-board system is easy to use, install, and maintain.  It is lightweight and robust for field deployment.  It includes software for waveform analysis and manipulation.

Its full-featured communication capabilities such as VSAT, ADSL, and some radios allows easy configuration for telemetry networks.  GSM, GPRS, CDMA, and PSTN communications are also supported.  The included GPS can act as a network timeserver for synchronizing other NTPv4 enabled timing critical systems, or the unit can use an external NTP timeserver.
