TSP3 Seismometers

Terrascience Short Period 1Hz Seismometer

The Terrascience Short Period sensor contains up to three high sensitivity, self-generating velocity detectors with extremely low natural frequencies. It is an excellent choice for detecting seismic activity for structural analysis, geologic hazards, vibration isolation, etc.

The TSP3 is available in 1.0 and 2.0 Hz natural frequencies and tri-axial as well as vertical or horizontal oriented models.  Sensitivities range from 3.0 to 15.0 V/in/sec depending on coil configurations. A weather-resistant cover (w/ level bubble), calibration coil, and adjustable leg bases are available. A vernier spring adjustment is included.
