What TJ|H2b Analytical Services does

TJ|H2b Analytical Services is a privately held specialty laboratory and diagnostic-services company headquartered in Sacramento, California, serving the high-voltage electrical equipment industry. The company performs standardized chemical and physical testing of transformer oils, insulating fluids, and SF6 gas using ASTM, IEC, and IEEE methods — including dissolved gas analysis, furan analysis, dielectric breakdown, particle counting, and corrosive-sulfur screening — and packages results into four proprietary diagnostic programs: Transformer Condition Assessment (TCA®), Tap Changer Activity Signature Analysis (TASA®), Breaker Oil Analysis (BOA®), and Breaker Gas Analysis (BGA®). These packages combine raw test data with expert interpretation and standardized condition codes that drive maintenance and replacement decisions for utilities.

The company operates an 11-laboratory global footprint spanning the United States, Canada, Australia, Malaysia, the Philippines, Norway, Spain, and Peru, supplemented by proprietary sampling hardware (the TFSS® turbulent-flush system and the stainless-steel GSCU for SF6 sampling) that it sells to customers to ensure sample integrity. Its go-to-market is a B2B enterprise motion: quote-based pricing, direct engagement with utility asset managers and reliability engineers, and an annual industry conference (TechCon® North America, running since 1996) that anchors its thought-leadership position. Revenue streams include laboratory diagnostic testing, proprietary diagnostic packages, proprietary sampling-equipment sales, and TechCon® registrations. The company is owned and led by its four founders, whose initials form the brand, and remains independently held with no disclosed outside investors.
