OSOP Calibration Table
Instrument response files have been called seismology's dirty little secret. Sensor gains are often copied from a datasheet and rarely checked. The OSOP Calibration Table checks them.
A portable step table for verifying the gain of seismometers and accelerometers, in the field, the vault or the lab. Designed after Erhard Wielandt's calibration table, it has no motor and needs no power supply. It checks the entire instrumentation chain.
Includes: calibration table with horizontal extension bridge, transport box, and osopcal software for determining gain from your calibration runs.
Works with broadband and short-period sensors, including Streckeisen STS-2, Streckeisen STS-2.5, Nanometrics Trillium Compact, Nanometrics Trillium 120, Metrozet, Reftek 151, Lennartz LE-3Dlite, Güralp CMG-3 and many others.
