What Global Test Supply does
Global Test Supply is a privately held, multi-brand e-commerce distributor of test and measurement instrumentation, headquartered in Wilmington, North Carolina with a secondary office in Wilmington, California. The company operates a portfolio of more than ten online storefronts anchored by GlobalTestSupply.com, which lists over 104,000 products from 300+ leading brands including Fluke, Mitutoyo, Testo, Honeywell BW, and FLIR, with a Member Store Extended Search tool that exposes an additional 300,000+ SKUs. Its corporate history consolidates legacy brands Calcert.com (rooted in Wilmington Instruments Company, est. 1944) and ValueTesters.com (est. 2003); both now operate under the Global Test Supply umbrella. The platform supports pay-as-you-go unit pricing, member-exclusive pricing with free shipping above $199, and assisted purchase via phone (1-888-610-7664), live chat, and email.
The company earns revenue across four streams: one-time product sales of instruments across electrical, gas detection, HVAC/R, pressure, temperature, dimensional measurement, and thermal imaging categories; ISO 17025:2017-accredited calibration services with NIST-traceable certificates; short- and long-term equipment rentals; and cost-effective repair services positioned as faster and cheaper than OEM repair. Distribution is primarily direct-to-consumer / SMB via the website, supplemented by an enterprise phone-sales channel and a network of specialized brand-dedicated storefronts (Fluke-Direct.com, Testo-Direct.com, CanarySense.com, PowerMeterStore.com, SHIMPO-Direct.com, Raytek-Direct.com, SENSIT-Direct.com). Customer-facing segments span industrial professionals, laboratory and research, automotive, firefighting, energy management, and home inspection, with a 4.8/5-star rating across 22,247 Shopper Approved reviews.
Global Test Supply is a family-run, bootstrapped private company with no disclosed funding, institutional investors, or public listing. It holds PCI DSS certification for payment processing and ISO 17025:2017 accreditation for its calibration laboratories (via Calcert.com lineage), and operates a Government Best Price Initiative targeting public-sector procurement. Geographic scope is primarily North America (US and Canada via ITM.com), with some product lines restricted from export by manufacturer contractual obligations. Headcount is reported at 1-10, indicating a lean operation that relies heavily on supplier drop-shipment, outsourced fulfillment, and automation to support a comparatively broad catalog and service surface.

Global Test Supply competitors and assessment
Company assessmentBroad incumbents
- Omega Engineering: Omega is a long-established broadline process measurement and control instrumentation supplier with its own catalog across temperature, pressure, flow, and electrical test. It overlaps with GTS on many industrial sensor and instrument categories.
- Grainger: Grainger is the dominant US MRO industrial distributor with a massive catalog including test & measurement instruments. While not a T&M specialist, it competes for the same industrial-buyer wallet and forces pricing pressure on smaller specialists like GTS.
- Newark Electronics: Newark (an Avnet company) is a broadline electronic component and test instrument distributor. It carries overlapping T&M brand lines and competes for the same industrial and laboratory purchasing budgets as Global Test Supply.
- Digi-Key Electronics: Digi-Key is a much larger global electronic component and test instrument distributor with millions of SKUs. It overlaps with GTS on Fluke, FLIR, and Testo product lines but serves a far broader electronics-design customer base and competes for the same SMB/industrial buyers.
- MSC Industrial Direct: MSC Industrial is a large US metalworking and MRO distributor carrying Fluke and other T&M brands. Competes with GTS for industrial MRO and maintenance test instrument purchasing across US manufacturing customers.
- Mouser Electronics: Mouser is a global broadline distributor of electronic components and test instruments with a similarly large catalog and similar authorized-distribution relationships. Competes with GTS for industrial test & measurement purchasing, especially for Fluke and Testo SKUs.
Direct peers
- Transcat: Transcat is the closest direct peer — an ISO-accredited calibration services provider that also distributes test & measurement instruments from brands like Fluke. Like GTS, it combines product distribution with accredited calibration and repair, competing head-to-head in the same T&M channel.
- Instrumart: Instrumart is an online T&M distributor carrying Fluke, Extech, Megger, and similar brands, with calibration services. Directly competes with Global Test Supply on multi-brand instrument distribution to industrial buyers.
- TestEquity: TestEquity is a direct e-commerce distributor of test and measurement equipment, including Fluke, Keysight, Tektronix, and other brands serving electronic test, environmental test, and calibration markets. Same product distribution model with calibration services overlap.
Regional players
- Pewatron: Pewatron is a European-based distributor of sensors, test & measurement, and power supplies serving OEMs and industrial customers. Comparable in product mix to GTS but operating primarily in European markets where GTS cannot sell under manufacturer territorial restrictions.
