Autonomous seismic data logger NDAS-8226

The NDAS-8226 autonomous seismic data logger is designed for autonomous data recording in field environments.

The model is based on a 6-channel 24-bit resolution ADC ensuring a low noise level. It uses a USB and Wi-Fi connection for data transfer and system configuring and a 32 GB internal memory storage.

NDAS-8226 includes a precision regulated VCO quartz crystal with the real-time GPS/GLONASS clock adjustment. This provides synchronization accuracy better than an error of timing of 1 µsec. The case is rugged and waterproof.

The model does not require any maintenance and is well-suited for field seismic and seismological surveys as well as for permanent seismic stations. It is perfectly compatible with R-sensors' products of CME, MTSS and METR series as well as any third-party equipment.
