STS-2.5
The World standard broadband-seismometer other seismometers are compared to, with very low noise, high clipping level, low power, and wide operational temperature range without adjustment.
A low temperature version (down to -55°C) is available on request.
Features
- Performance equally to STS-2
- Improved insensitivity to barometric pressure variation by a factor of 10 compared to STS-2
- Serial interface for control and maintenance
- Auxiliary signals switchable between mass-position and UVW-raw
- Low power, less than 450 mW
