Shaketable

To calibrate a sensor it is necessary to simulate an earthquake. The equipment of choice is a shaketable. We use a custom-built equipment that is able to shake all three components in one run.

Test vault

Completely assembled seismometers are being checked during several weeks. Large shielded granite slabs allow simultaneous measurements on many units.
For electric and magnetic capability we use an anechoic chamber and a three dimensional Helmholtz coil.
To test our low temperature versions we operate a very low temperature fridge (-80°C).

Quiet Sites

Long term testing and STS-6 production tests are carried out at our remote quiet site. It's a former WW2 fortress within stable rock and thus shielded to influences by nature or human as far as being possible in Switzerland.

We further have collaborating access to some of the most quiet sites in the world for advanced performance tests.
