What SM does

SM Srl, operating as SM Instruments, is an Italian precision metrology manufacturer founded in 1984 and headquartered in Volpiano (Turin), Italy. The company designs and manufactures instruments for the characterization of surfaces, dimensional errors, and quality assurance. Its product portfolio spans three instrument families: portable and laboratory roughness testers (LITEsurf, RT10G, RTP80, WARPsurf, RT120); profilometers (PGS100, PGS200); and roundness testers (R100, R250, R300, R500, plus the RunOut Machine). These instruments integrate proprietary software — Circom for roundness and geometric tolerance analysis, Profile Studio for combined roughness and profile measurement, and Measurement Studio for portable tester data management — built on precision mechanical engineering and measurement algorithms compliant with ISO 4287, ISO 13565, ISO 12085, and VDA 2007 standards.

Revenue is generated through one-time hardware sales of precision instruments, perpetual software licenses bundled with hardware, ACCREDIA-accredited calibration and certification services under laboratory LAT N 041, retrofit modernization kits that upgrade obsolete instruments from other manufacturers, and the sale of calibration specimens. SM serves three identifiable segments: industrial manufacturers requiring surface and dimensional quality control (primary), energy-sector customers measuring large rotating components such as gas turbine rotors (via the R500 and RunOut Machine), and metrological laboratories requiring accredited calibration. Distribution is direct to enterprise and quality-control professionals; no reseller, distributor, or marketplace channels are evident, and disclosed geographic scope is limited to Italy. Pricing is not publicly disclosed; customers are directed to request quotes.

The company operates an in-house ACCREDIA-accredited metrological laboratory providing ISO/IEC 17025-compliant calibration certificates recognized internationally through EA and ILAC-MRA mutual recognition, and runs a niche retrofit business that ties legacy installed bases of competitors' instruments to SM's updated electronics and software. Headcount is reported at 11-50 employees, share capital stands at €51,948 (fully paid), and no public listing or external funding has been disclosed. Management is led by the Caprioglio family, with Cristian Caprioglio serving as Manager of the ACCREDIA Calibration Laboratory.

Revenue model

1. Precision Measurement Instruments: Sale of roughness testers, roundness testers, and profilometers. Instruments range from portable palm-sized units (LITEsurf, RT10G) to large laboratory-grade systems (R300, R500). Revenue is generated through one-time hardware sales with no recurring revenue component mentioned.
2. Software Licenses: Proprietary software products including Circom, Profile Studio, and Measurement Studio are sold as perpetual licenses with the instruments. Some software also sold separately (e.g., Profile Studio code 1.407 for WARPsurf).
3. Calibration and Certification Services: ACCREDIA-accredited metrological laboratory performs calibration and certification services for measurement instruments and specimens. Services include internal calibration reports and external calibrations at customer sites. Also issues calibration certificates compliant with UNI EN ISO 10012 and UNI EN ISO 9001-2008 standards.
4. Retrofit and Modernization Services: Upgrade kits that modernize obsolete measurement instruments by replacing old electronics with new control systems and installing latest-generation analysis software. Also includes mechanical cleaning and inspection services.
5. Calibration Specimens: Sale of calibration specimens for roughness, roundness, and profilometry instruments. Specimens include hemisphere samples, Guizzo specimens, cylindrical specimens, and reference artifacts. Calibration certificates available upon request.
