Since 1838, Troemner has enjoyed a long history as the leader in the field of precision measurements. Over the years, Troemner has enhanced its reputation as being the premier company in the metrology industry by achieving ISO 9001 certification, and accreditation in our laboratories by both the National Institute of Standards and Technology (NIST) administered National Voluntary Laboratory Accreditation Program (NVLAP) and the United Kingdom Accreditation Service (UKAS). Troemner strives for excellence in every area of the business, and continues to raise the standards of the industry.
Troemner offers the most comprehensive selection of precision weights and mass standards. Our weight selection includes every imaginable size and type from 5000 lb cast iron test weights to the extremely precise, highly polished one and two-piece stainless steel weights. At Troemner, careful attention is paid to every detail of production. Weight bottoms are slightly recessed to expose the smallest possible area to wear. Weight heads and necks are precisely shaped to give a solid, sure grip to forceps or weight lifters. Troemner uses the finest materials available for the production of all of our weights and mass standards. For your most demanding applications, our precision weights are manufactured from Troemner Alloy 8, which is a specially developed stainless steel. Troemner Alloy 8 possesses closely controlled density, extremely low magnetic permeability, good stability and resistance to corrosion and handling damage. We manufacture and calibrate weights to meet or exceed the highest tolerance standards of ANSI/ASTM, OIML and NIST.
Troemner’s Calibration Laboratories provide our customers with all the data and traceability information they need for their calibration items. Troemner is committed to achieving the highest levels of accreditation for all its calibration technologies. Since 1995, both NVLAP and UKAS have accredited Troemner's Mass Calibration Laboratories. Troemner offers either NVLAP or UKAS calibration and certificates for precision weights. Troemner’s Mass Calibration Laboratories can also provide NVLAP accredited mass magnetic susceptibility and density determinations for precision weights. Troemner was the first company in the United States to be accredited by NVLAP for Pipette calibrations and certificates. Troemner’s NVLAP accreditation has expanded to meet the diverse needs of our customers and now includes the Humidity Calibration Service, Pressure Calibration Service, and Temperature Calibration Service (for comparison temperature calibrations). Troemner’s Thermal Mass Flow Calibration Service is performed in an ISO/IEC 17025 compliant laboratory. New services, including Electrical, Time and Frequency, are being added to ensure we are meeting all of the unique needs of our customers.

Henry Troemner founded Troemner over 160 years ago in 1838. The company started as a manufacturer of scales and weights in Philadelphia, Pennsylvania. From the beginning, Troemner earned a reputation for being a manufacturer with high quality standards. In 1856, Troemner received a contract to make scales for the U.S. Mint in Philadelphia. The success of this contract led the company to expand its product line of scales to include bankers' scales, precision weighing equipment for jewelers, prescription scales for pharmacists, and laboratory scales and balances for chemists.
By the time of Henry Troemner's death in 1873, the Troemner name had become internationally respected in the commercial world of weights and balances. The company was inherited by Henry Troemner's sons and remained a family business for three generations until 1955.
In 1955, Mr. Laird Park purchased the company from the Troemner family. At this time, the company needed to be revitalized to return to its former glory. Mr. Park brought his knowledge, experience and enthusiasm to this venture to bring Troemner into the 20th century. Under his direction, the balance and scale product line was updated to meet market demand and the production of precision weights began in earnest. In 1958 Troemner published its first comprehensive catalog of standard weights. Troemner next offered its own weight calibration service for customer weights. This important service is one that continues to this day.
In addition to updating Troemner's products and services, Mr. Park rehabilitated Troemner's facilities. In 1963 Troemner moved to 6825 Greenway Avenue in Philadelphia. At this site, Mr. Park expanded and increased efficiency in a modern manufacturing facility for Troemner's products.
During this time Troemner entered into the field of manufacturing laboratory equipment. This product line started with a series of magnetic stirrers, and grew to include hotplates and combination hotplate/stirrers of various sizes. As Mr. Park continued to grow Troemner's customer base, he realized there was a need in the industry for gas cylinder safety products and he added those items to Troemner's growing product line.
In the 1990's, Troemner began the process of achieving ISO 9001 certification. Troemner was one of the first companies in the Philadelphia area to earn ISO 9001 certification in 1993. Shortly after this milestone, Troemner began the process of gaining accreditation of its mass metrology laboratories by the NIST administered National Voluntary Laboratory Accreditation Program (NVLAP) and its United Kingdom equivalent, United Kingdom Accreditation Service (UKAS, formerly known as NAMAS). By obtaining accreditation, Troemner is able to provide our customers with certificates that meet or exceed the strictest recognized standards.
In 1995 Mr. Park officially retired and Mr. Abele who joined Troemner in 1972 became Troemner’s new owner. In May 1999, Troemner moved across the Delaware River to Thorofare, New Jersey.
