What All-Test Pro does
ALL-TEST Pro (ALL-TEST Pro, LLC), headquartered in Old Saybrook, Connecticut, is a privately held niche industrial instrumentation manufacturer specializing in electric motor testing and predictive maintenance (PdM) equipment. Founded in 1985, the company serves a broad industrial base — including utilities, food and beverage manufacturers, electrical and instrumentation contractors, EV operators, and predictive maintenance service providers — across virtually every sector that relies on rotating equipment such as motors, generators, and transformers. The firm operates with 11-50 employees and distributes worldwide through direct sales, a regional distributor network, and an online storefront.
The company's product platform is built on two proprietary diagnostic methods: Motor Circuit Analysis (MCA™), a patented deenergized testing technique, and Electrical Signature Analysis (ESA), an energized testing approach. These methodologies underpin a hardware portfolio of handheld instruments (AT7 Pro, AT7, AT34, AT34 EV, Motor Genie MCA), the ATPOL III power quality analyzer, the MD III assembly integrating both methods, and accessories and supporting software (AT31 Condition Calculator, ATIV TREND/EMCAT PRO, AT33 IND V3). The company holds multiple patents including TVS™ transient voltage suppression technology, and its instruments have been field-deployed in customer environments for over 30 years, providing non-destructive diagnostics of ground faults, winding faults, rotor faults, open connections, and contamination.
ALL-TEST Pro monetizes primarily through quote-based hardware sales, supplemented by training services (one-on-one onsite, virtual orientations, and motor diagnostic seminars), calibration and repair services, and leasing and rent-to-own financing options. Pricing is not publicly disclosed; the company website is localized in 19+ languages to support its worldwide distributor channel. The publicly visible customer base includes named enterprise accounts across utilities (Entergy), food and beverage (Herdez/Barilla Mexico), electrical contracting (Dalton E&I), manufacturing (Technocast), and predictive maintenance services (Humboldt Mfg), suggesting revenue diversification across verticals rather than dependence on a single anchor account.
