What D.Marchiori does

D.Marchiori s.r.l. (DMA), founded in 1938 and headquartered in Aprilia, Italy, is a precision aircraft ground test equipment manufacturer whose products are deployed in more than 80 countries. The firm's core offering is the RVSM-compliant Air Data Test Set (ADTS) family — including the MPS43, MPS50, MPS62, and the newly introduced MPS63 — used for testing, troubleshooting, leak-testing, and certifying aircraft pitot-static systems. The underlying technology is based on digital control systems paired with vibrating cylinder resonant transducers and individually characterized high-quality silicon diaphragm piezo-resistive transducers, achieving linearity errors below 30 ppm full scale, plus features such as multiple isolators for simultaneous multi-system testing, ultra-low airspeed function for helicopter testing (5–200 kts), and self-contained battery operation of up to four hours. The portfolio extends to pitot-static adapters and accessory kits (often described as the only single-vendor integrated ADTS-plus-adapter solution), pressure/vacuum generators (EPSR series), pressure indicators and transfer standards (PAMB11H), pressure chambers (CBA8), pressure calibration standards (MM14-BW), tachometer testers (BCE series), 3-axis tilt tables (MTG7), angular protractors (IAC90) for fly-by-wire control surface analysis, safety valve testers (DMSV1), and pitot-heat alert devices (ADTA series).

The company monetizes through multiple streams: capital hardware sales (ADTS, adapters, AGSE), factory-direct OEM and EN-ISO 17025 accredited calibration services (including the newer FAST LANE priority service), recurring spare parts, and operator training courses. DMA holds ISO 9001:2015 quality certification and operates an Accredia-accredited laboratory (00145 LAT, renewed 30 September 2025) that is signatory to ILAC/EA/IAF mutual recognition. Distribution is via a global dealer network plus direct factory sales for service, supported by an online Product Finder for adapter compatibility. Customers include civil airlines, MRO overhaul bases, helicopter operators, and general aviation users, with no single named customer dominating public disclosures.
