What Henry Troemner does
Henry Troemner (operating as TROEMNER, LLC) is a U.S.-based precision calibration weights manufacturer and weight calibration service provider, founded in 1838 and headquartered in the Greater Philadelphia/Greater New Jersey area (Thorofare, NJ). The company manufactures calibration weights spanning ANSI/ASTM E617 Classes 000 through 7, OIML R 111 Classes E0* through M3, and NIST Class F, as well as custom weight products, weight cases, and weight carts. Its proprietary technology stack centers on Troemner Alloy 8 — a stainless steel with controlled density (8.03 g/cm³), low magnetic permeability, and corrosion resistance — and the exclusive UltraClass weight series (Platinum, Gold, and Standard), which meet or exceed international metrology tolerances. Calibration is performed in ISO/IEC 17025-accredited laboratories (NVLAP Laboratory Code 105013-0) using robotic mass comparator systems in purpose-built "building within a building" facilities with vibration isolation, dedicated HVAC, and vapor barriers.
The company operates a B2B direct sales model, selling one-time calibration weight products through its troemner.com e-commerce storefront and generating recurring revenue through professional weight calibration services. Products are available with ISO/IEC 17025 accredited certificates, traceable certificates, or without certificates at lower price points; custom products require quote-based pricing. Troemner serves calibration and metrology laboratories, pharmaceutical and life sciences organizations (USP Chapter 41 compliance), manufacturing and industrial quality control operations, state and local weights and measures officials, and educational institutions. The company is a subsidiary of OHAUS Corporation, and in August 2025 it acquired the Genie Division from Scientific Industries for $9.6 million plus potential earnouts, signaling portfolio expansion beyond traditional calibration weights. The company maintains ISO 9001 quality management certification and distributes globally through its own website and direct sales channels, with no apparent third-party distribution.
