Calibration and Repair Service

Our repair and calibration department can handle all of your seismograph service needs.  Please use the RMA system when sending in instruments for repair and calibration.  Also, do not include accessories such as spikes, microphone stand, etc as we will not be responsible for the return of those items.  All you need to send is the instrument, transducer package and microphone.

We perform a very thorough checkup of every seismograph.  We test the batteries, clean the connectors, examine the boards for corrosion and perform other function tests.  Our calibration equipment is traceable to NIST and our reference equipment is independently calibrated regularly.
