Established in 1838, Troemner has continually enhanced its reputation through personnel, refined and accredited processes, and equipment to become the premier manufacturer of precision weights. The Troemner staff includes on premises, industry recognized metrologists and highly trained calibrators. Troemner weights are manufactured in a state-of-the-art facility using the finest materials and equipment available. For these significant reasons, Troemner is capable of providing unmatched measurements and metrological analysis and to provide customers with unmatched precision in weights.

People with Experience

We have been manufacturing weights and conducting mass measurements for over 170 years! We have four full-time industry recognized metrologists on staff who track and control our measurement processes to assure superior quality. Being the largest private mass metrology laboratory in the world, no one makes more mass measurements per day than Troemner. Like anything else, with repetition comes learning, refinement and constant improvement.

World Class Laboratories

Our mass laboratories were specifically constructed to create an environment of stable temperature and humidity, low vibrations, and low air velocity, which is suitable for making precise mass measurements. Troemner's Class I Laboratory is the largest private mass metrology laboratory in the world.

State-of-the-Art Equipment

Troemner has the largest collection of mass comparators in the world, and we are constantly purchasing new comparators to keep our capabilities up to date to maintain the highest level of precision. Additionally, seven newly acquired robots allow Troemner to provide impeccable service by increasing not only precision, but also efficiency. We also use proprietary software to track the performance of our equipment and standards to assure that our calibration system is in control. Magnetic permeability testing and magnetic susceptibility testing are incorporated into our processes and utilize a susceptometer.


We select only the finest raw materials in order to manufacture high quality weights. Troemner is the only supplier that has a special stainless steel blend called Troemner Alloy 8, which possesses closely controlled density (8.03 g/cm3), extremely low magnetic properties, excellent stability and very high resistance to corrosion.

Troemner's Beginning

Henry Troemner Henry Troemner Troemner started as a manufacturer of scales, balances and weights in Philadelphia, Pennsylvania. Henry Troemner, a German immigrant, was originally a locksmith and learned the balance craft after he arrived in Philadelphia.

From the beginning, Troemner earned the reputation of being a manufacturer of high quality products. The business grew steadily after the discovery of gold in California on January 24, 1848, as the company was known for its bullion and assay balances. Henry Troemner's three sons continued to develop and grow the business, and by the early 1900's Troemner was recognized internationally as a world leader in the balance and scale manufacturing industry.

During the 1950's Troemner's balance and scale product line was updated to meet market demand and the production of precision weights became a larger part of its overall business. In 1958, Troemner published the company's first comprehensive catalog of standard weights and began to offer a weight calibration service for customers' weights. This important service is one that continues to this day.

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 the National Institute of Standards and Technology (NIST) administered National Voluntary Laboratory Accreditation Program (NVLAP*).

Troemner Today

troemner Over the years Troemner has continued to expand and increase its expertise in manufacturing and measurement capabilities. Troemner relocated to Thorofare, NJ on May 1, 1999 to a state-of-the-art specially designed corporate headquarters. The headquarters were planned by a team of employees, engineers, and architects to specifically meet the customers' needs for high precision calibrations. Troemner's laboratories provide customers with all the data and traceability information they need for their calibration items. The Calibration Laboratories' physical environment and state-of-the-art equipment enable Troemner to produce measurements with the lowest possible uncertainties rivaling, and in some cases exceeding, those of National Measurement Institutes.

Troemner is not only committed to quality calibrations but to the product itself as evidenced by the introduction of a unique material used to manufacture weights called Troemner Alloy 8. Troemner Alloy 8 possesses closely controlled density (8.03 g/cm3), extremely low magnetic properties, excellent stability, and very high resistance to corrosion. Troemner is committed to achieving the highest levels of accreditation for all of our calibration services which include mass, mass magnetic susceptibility, mass density determination, pipettes, temperature, humidity, pressure, thermal mass flow, electrical, dimensional, time and frequency. We continue to research and add new calibration services to meet the diverse needs of our customers.

We have continued to expand and increase our expertise in manufacturing and measurement capabilities. In addition to our weights and calibration services, Troemner broadened its expertise into the development and manufacture of a full line of laboratory equipment. For over 50 years we have been a leading provider of reliable, high quality laboratory equipment products. As the needs of our customers have changed we have added to our product line. In 2000, Troemner acquired the Talboys overhead mixer product line and we have expanded the laboratory equipment offering to meet the unique needs of our customers.

Today Troemner's Talboys laboratory equipment products include shakers, incubating shakers, vortex mixers, hotplates, stirrers, dry block heaters, overhead mixers, homogenizers, microplate stability chambers, and clamps. Our Talboys equipment products are manufactured under an ISO 9001 accredited quality system. Many of the products are TUV, UL, CUL, CSA, and CE certified. Troemner strives to provide our customers with exactly what they need to run their laboratories efficiently and safely.
