Ainsworth is one of the oldest manufacturers of precision analytical balances in the world. The company was founded in 1880 at the height of the legendary Colorado goldrush. The company founder, William Ainsworth, recognized the opportunity for a U.S. manufacturer and entered the market with innovative analytical balance designs.

In the past century, the Ainsworth product line has featured a variety of products including military compasses and watches. Balances and scales, however, have always been the foundation of the company. Through the years, mechanical balances, jeweler scales and postal scales have been successful under the Ainsworth name. The current product line includes a broad range of electronic precision analytical and toploading balances, portable balances, high-capacity industrial scales and infrared moisture analyzers.

Ainsworth continues to design balances to meet modern weighing requirements. The latest, the P-Series, is the first balance on the market to include a USB port, a new interface for peripheral devices. The Ainsworth company has always valued research and development. Ainsworth is committed to bringing products to the customer that are relevant for current needs. In 1880, William Ainsworth believed in providing high-quality products at reasonable prices. This philosophy is still true today.
