Ultra low power recorder (ULPR) for geophysical Exploration
ULPR is a 31 bits two or three channels precise AD data logger for Geophysical application with the features below. The current version is mainly designed for the measurement for the following application examples:
- Random distributed SP and microearthquake exploration for geothermal
- Controlled source electrical or electromagnetic exploration
- Microearthquake using multiple geophones or seismometers
- Random distributed active seismic exploration
- Broad Band MT (400 Hz ~ 0.00001 Hz) with broadband magnetometer
For Geotech civil engineering application:
- SP and Spectral Analysis of Surface Wave for contamination
- SP and microearthquake monitoring for land slide
Main Features:
- Two different models:
- ULPRx3 for 3-chennels
