STS-2 (legacy product)
Despite its age, the STS-2 is still a high performance broadband-seismometer. Three versions exist: Standard, High Gain and Low Power. The latter is the most common one.
Although the sensor is obsoleted since 2010 we still provide a limited support. Repairs however are not possible anymore.
Features
- First available triaxial broadband seismometer
- Manufactured between 1991 und 2010
- Only very limited support
(Cables and hostboxes are available until we run out of stock)
