What Technical Maintenance, Inc. does

Technical Maintenance, Inc. (TMI Calibration) is a US-headquartered, founder-owned, full-service NIST-traceable calibration laboratory founded in 1991 by Wendy and Mike Floyd. Operating under ISO/IEC 17025:2017 accreditation through A2LA/ANAB, TMI provides accredited calibration, repair, and asset management services for electronic, mechanical, optical, physical-dimensional, and telecommunications test and measurement equipment across 11-12 company-owned laboratories plus an on-site technical services (OTS) division that runs customer-facility calibration labs. Its core technology stack is the calibration laboratory itself: NIST-traceable reference standards, measurement uncertainty workflows aligned with ANSI/NCSL Z540-1 and Z540.3, nuclear 10CFR50/10CFR21 and AS9100 compliance, and an IndySoft-powered customer portal for certificate and asset tracking.

TMI monetizes through four streams: (1) tiered calibration services (Basic, Calibration with Data, and ISO/IEC 17025 / Z540.3 accredited calibration) priced per quote, (2) accredited repair services with a 90-day warranty, (3) managed asset management and on-site calibration contracts, and (4) new equipment sales via authorized distribution partnerships (Mitutoyo CMMs, Fluke, AEMC, Omega, Rice Lake, Hexagon, and others). Customer segmentation is horizontal across industrial manufacturing (primary), pharmaceutical / healthcare (cleanroom and biosafety cabinet certification), and telecommunications (fiber optic and Sonet/SDH/PDH calibration), with go-to-market executed through regional sales managers (Eastern and Western USA), branch managers at each lab, account managers, trade shows (A2LA, NC SLI, The Quality Show), a quarterly newsletter, and customer satisfaction surveys.

The company is private, founder-controlled with Floyd family members in branch and sales roles (Taylor Floyd in NC, Austin Floyd on Clean Room, Brian Floyd as account manager), has no disclosed outside equity or debt, and operates entirely domestically across the Southeast, Midwest, Northeast, Southwest, and Mountain West regions of the United States.

Broad incumbents

• Rohde & Schwarz: German test and measurement OEM offering factory calibration for RF/microwave, wireless, and aerospace/defense test equipment. Directly competes in TMI's highest-frequency calibration segment and provides an OEM service alternative for telecom and aerospace customers.
• Tektronix: Test and measurement OEM providing factory-authorized calibration for oscilloscopes, signal generators, and spectrum analyzers. Competes with TMI's electronic calibration capability for OEM-preferred service work in industrial and aerospace customers.
• Fluke Calibration: Calibration instrumentation and services subsidiary of Fortive, also a TMI distribution partner for Fluke test equipment. Competes on electrical, RF, pressure, and temperature calibration but primarily through OEM service depots rather than independent labs.
• Keysight Technologies: Major electronic test and measurement OEM with a calibration services division covering RF/microwave and electronic instruments. Overlaps directly with TMI's 50 GHz electronic calibration capability, but Keysight's scale and direct factory service represent both competitor and customer-referral partner.
• Yokogawa Electric: Process automation and measurement OEM with calibration service programs for industrial process instrumentation. Comparable to TMI on pressure, temperature, and electrical calibration for power, oil & gas, and chemical customers, though broader in scope.

Direct peers

• Trescal: Global pure-play calibration services provider backed by private equity, with operations across the Americas, Europe, and Asia. Directly comparable on multi-discipline ISO 17025 calibration, on-site services, and aerospace/defense customers; materially larger scale than TMI.
• Transcat: NASDAQ-listed commercial calibration services provider operating national lab and on-site service network across the US and Canada. Closest direct competitor to TMI by service model (NIST-traceable calibration, repair, asset management) and customer base in industrial, aerospace, and life sciences.
• Beamex: Finland-headquartered calibration solutions company offering both calibration instruments and accredited calibration services for process industries. Overlaps with TMI's physical dimensional / pressure / temperature capabilities and targets similar regulated industrial customers.
