What PAC does

PAC L.P. is a Houston, Texas-based privately held manufacturer of advanced analytical instruments for laboratory and online process applications, founded in 1995 and operating across oil and gas refining, petrochemicals, aviation and jet fuel, marine, renewable fuels, MedTech, EV battery, automotive, pharmaceutical, food and beverage, and offshore/environmental sectors. Its product portfolio spans gas chromatography, distillation analyzers, viscometers, flash point testers, cold properties analyzers, elemental analyzers (UV fluorescence and chemiluminescence), oil-in-water and water-cut monitors, and leak-testing systems, organized under 11+ wholly owned sub-brands including Uson, Cambridge Viscosity, ISL, Herzog, Advanced Sensors, Icon Scientific, Phase Technology, AC Analytical Controls, Antek, Alcor, and Emcee Electronics. Flagship offerings include the 70Xe Series integrated multi-parameter fuel analyzer and the JFTOT IV jet fuel thermal oxidation tester, both built around proprietary method-standard architectures compliant with ASTM, ISO, EN, DIN, GPA, IP, UOP, DEF STAN, and other international standards.

The PACe digital platform overlays the installed instrument base with asset management, real-time analytics, predictive maintenance, and cost/capacity forecasting, introducing a recurring software and data revenue stream on top of the traditional capital-equipment model. PAC monetizes through one-time instrument sales (benchtop and process analyzers), aftermarket services and consumables (parts, calibration, IQ/OQ qualification, training), and emerging PACe subscriptions, distributed via 13 direct sales and support offices and a network of over 140 independent distributors across North America, Europe, the Middle East, India, Singapore, China, and South Korea. The company has grown consistently through a multi-decade acquisition strategy, most recently adding Emcee Electronics in 2025 to deepen aviation fuel testing capability.
