The Marchetti Add-on Acquisiton unit connects to the side of a traditional mechanical-only DMT control unit, which is not in production since 2015.
This combination provides the same functionalities of the Control Unit.
A USB connection to a laptop computer (not included) enables the automatic acquisition of DMT pressure readings and to record seismic waves using an Marchetti SDMT probe.
