MidLine 2 Hz Borehole Seismometer – Gimballed
The AG2 is ASIR's readily deployed three-component 2 Hz gimballed borehole seismometer designed for high-sensitivity microseismic and earthquake monitoring in deep boreholes. The sensor is suitable for permanent or temporary installations to depths of up to 3000 m and accommodates borehole deviations of up to 15° through its precision gimballed suspension. Combined with ASIR's mechanical hole-lock system, the AG2 delivers reliable long-term performance for geothermal energy, mining, carbon storage (CCS), oil and gas, and scientific research applications.
Advanced Features
- slim 61 mm outer diameter (OD)
