Humboldt began operations in 1909 as a manufacturer of cement testing equipment in the Humboldt Park neighborhood of Chicago, IL — establishing from the beginning, a solid reputation for producing high-quality, scientific products, as well as providing excellent customer service. During World War II, Humboldt expanded its manufacturing operations to meet the demand for general laboratory equipment and began manufacturing a line of top-quality labware, which included Bunsen and high-temperature burners. These products were the beginning of Humboldt’s general laboratory equipment line of laboratory burners, stands and clamps. Since 1990, under the direction of Dennis Burgess, Humboldt has consistently grown, introducing new equipment, expanding into new testing equipment markets and expanding our sales and dealer channels. During these years Humboldt has transformed into the company we are today, an employee-owned company, focused on the development, manufacturing and distribution of construction materials testing equipment throughout the world.
