Microphone Calibration

We have different types of calibrators available for checking calibrationvalues of microphones before (& after) measurement sessions.

Some types are calibrators for "on location" use and others for laboratory use.

You can find a little information on different calibration techniques in Microphone Calibration for accurate Sound Measurements []
