The global test and measurement equipment market was valued at USD 19.06 billion in 2025 and is sized at USD 19.84 billion in 2026, heading to USD 24.27 billion by 2031 at a 4.11% CAGR, per Mordor Intelligence reporting dated February 16, 2026 [S1]. Vendor concentration is led by Keysight Technologies, Fortive Corporation, AMETEK, Rohde & Schwarz, National Instruments (NI), and Teledyne, identified as the dominant suppliers of test and measurement equipment by Fortune Business Insights [S4].
Inside the wider industrial-instrument scope, the measuring and control instruments market was valued at USD 78.6 billion in 2024 and is projected to reach USD 110.2 billion by 2030 at a 5.8% CAGR [S3].
Vendor Concentration and the Top Six OEMs
Fortune Business Insights names Keysight, Fortive, AMETEK, Rohde & Schwarz, NI, and Teledyne as the dominant players in the test and measurement equipment market [S4]. These six vendors cover the bulk of benchtop and modular electronic test, with Keysight and Rohde & Schwarz anchored in RF and wireless, Fortive (Fluke/Tektronix family) and Teledyne (LeCroy) in general-purpose bench, AMETEK in process and calibration, and NI in modular PXI-based architectures [S4]. Mordor Intelligence's driver table reinforces Keysight's positioning, noting that Keysight disclosed double-digit automotive revenue growth in fiscal 2025, driven by 800 V and 1,200 V EV architecture validation demand [S1].
Market-reportsworld pegs the global Test and Measuring Instruments market at USD 19,562.7 million in 2026, growing to USD 32,022.6 million by 2035 at a 5.63% CAGR, a slightly higher trajectory than Mordor's, reflecting different instrument scopes counted in each study [S2]. North America holds the largest regional share at 32%, while Asia grows fastest at a 6.8% CAGR through the forecast window [S2].
Product Mix: General Purpose Leads, Modular Climbs
General Purpose Test Equipment led the test and measurement market with 35.67% share in 2025, while Modular Instrumentation is forecast to advance at a 5.44% CAGR through 2031 [S1]. Calibration Services captured 39.33% of 2025 service revenue, the single largest service line, with Asset Management and Rental Services projected at a 5.12% CAGR over 2026 to 2031 [S1].
In the parallel Market-reportsworld taxonomy, multimeters lead with 35% share and spectrum analyzers are the fastest-growing segment at a 6.1% CAGR [S2]. Electronics dominates application share at 40%, supported by semiconductor test demand [S2]. More than 50% of industrial users are adopting connected testing solutions to improve operational visibility and reduce manual inspection, per the same source [S2]. These figures map cleanly onto flow meter, pressure transmitter, and vision measuring machine procurement in process and discrete plants, where digital output and IIoT connectivity are now baseline specification language.
Form Factor and End-User Split
Benchtop and rack-mounted instruments still hold 45.76% of 2025 test and measurement revenue, the largest form-factor bucket, while embedded and in-system test modules are set to grow at a 5.03% CAGR through 2031 as automotive and aerospace OEMs shift toward reconfigurable test cells [S1]. Telecommunications and IT held 28.91% of 2025 revenue, the top end-user industry, while automotive and transportation are poised to grow fastest at a 5.67% CAGR over the same period [S1].
More than 40% of industrial testing applications in the United States are associated with electronics, telecommunications, and automotive sectors [S2]. Approximately 45% of field testing applications now prefer compact portable and handheld instruments, a form-factor shift that benefits vendors with deep handheld oscilloscope and thermal-imaging lines, including the Fluke and Teledyne families under Fortive and Teledyne's respective umbrellas [S2][S4].
Regional Map: Asia Pacific Leads Revenue, Middle East the Fastest Mover
Asia Pacific captured 32.46% of 2025 test and measurement revenue, the largest regional share, with the Middle East projected to record a 5.23% CAGR through 2031 as national technology programs diversify away from hydrocarbons [S1]. North America is the largest regional Test and Measuring Instruments market at 32% share, while Asia grows fastest at 6.8% CAGR through the Market-reportsworld forecast [S2].
Demand drivers are tightly correlated with regional end markets: automotive E-mobility adds an estimated +0.9% to CAGR in China, Europe, and North America; 5G and 6G mmWave roll-outs add +0.8%, concentrated in Asia Pacific with spillover to the Middle East and Latin America; and AI-enabled design-for-test tools add +0.7% in Taiwan, South Korea, and the United States [S1]. These regional clusters line up with the manufacturing geographies behind pressure, flow, and level instruments, including pressure sensor and industrial valve supply, where the same end-customers (chemical, oil and gas, water) are rewriting calibration cycles around EV-battery and 5G base-station capacity additions.
Selection Criteria Buyers Are Using in 2026
Procurement teams in 2026 are weighing four decision criteria: total cost of ownership (purchase plus 5-year calibration), bandwidth or measurement range, interoperability with the existing SCADA or PXI chassis, and regional service coverage [S1][S3]. Modular instruments win on the third and fourth criteria for aerospace and EV OEMs reconfiguring test cells, while benchtop still wins on raw bandwidth and noise floor for RF and oscilloscope applications [S1].
Below is a criteria-based comparison of the three main instrument categories procurement is splitting spend across, grounded in the research material:
General Purpose Test Equipment: 35.67% of 2025 T&M share; widest vendor base including Fluke, Keysight, Rohde & Schwarz, Tektronix; lowest unit cost; weakest modularity and lifecycle upgrade path [S1][S4].
Modular Instrumentation (PXI, AXIe, LXI): 5.44% CAGR through 2031, fastest of the three; high reconfigurability for EV and aerospace validation cells; software-defined; higher integration cost and steeper learning curve [S1].
Embedded and In-System Test Modules: 5.03% CAGR through 2031; designed for board-level and production-line test; smallest standalone share but highest unit volumes per OEM line; tied closely to semiconductor capex [S1][S7].
The calibration services layer, 39.33% of 2025 service revenue, is the recurring-revenue line that vendors like AMETEK and Fluke lean into, and the segment most directly tied to ISO 17025-accredited lab footprints in each region [S1].
Limitations, Failure Modes, and Sourcing Discipline
Five-year revenue forecasts in this category diverge by roughly USD 8 billion between Mordor's USD 24.27 billion (2031) and Market-reportsworld's USD 32.02 billion (2035), reflecting differences in instrument scope, currency treatment, and whether service revenue is bundled [S1][S2]. Procurement teams should treat the higher figure as the upside case and the lower figure as the baseline when sizing multi-year calibration contracts.
Adoption-rate claims also vary: Mordor notes modular instrumentation at a 5.44% CAGR but does not publish an installed-base share, while Market-reportsworld claims 50% of industrial users are adopting connected testing solutions without providing a baseline year [S1][S2]. Both figures are useful as directional indicators but should not be quoted as installed-base penetration without primary OEM confirmation. A practical watch-list signal for sourcing teams is the EMC and EMI norms tightening for medical electronics, which Mordor pegs as a +0.4% CAGR driver in North America with influence in Europe and Japan, a regulatory lever that will force replacement cycles in legacy medical-instrument test racks through 2027 [S1].
For related context on how programmable DC power supplies are being sized for these same EV and 5G test cells, the programmable DC power supply sizing and selection guide walks through voltage, current, and ripple budgets that match the 800 V and 1,200 V architectures driving Keysight's automotive growth [S1]. For inductive proximity sensors used in fixture and handler automation alongside these test cells, the inductive sensor sizing and selection guide covers Sn, target material, and housing trade-offs that procurement teams weigh against the same vendor map. The semiconductor capex underpinning embedded and in-system test growth, USD 113 billion in OEM sales projected for 2024 by market.us, is the upstream demand signal that vendors like NI, Keysight, and Teledyne are positioning modular PXI and AXIe product lines to capture [S7].
