Foster Instruments delivers on-site audiometric testing to Illinois manufacturers, food processors, heavy-equipment plants, and warehouses. CAOHC-certified technicians arrive with the mobile booth, audiometer, and OSHA-ready paperwork.
Built for Illinois Industrial Employers
Illinois manufacturers — heavy equipment, food processing, metal fabrication, plastics, pharmaceuticals, and the largest concentration of warehousing in the Midwest — have hundreds of thousands of noise-exposed workers under OSHA 1910.95. Foster Instruments delivers the entire audiometric program on-site so your Illinois facility stays compliant without losing a shift.
We regularly serve facilities across Chicago, Aurora, Rockford, Joliet, Naperville, Peoria, Springfield, Elgin, Waukegan, Champaign, Bloomington, Decatur, Schaumburg, and the I-80 / I-55 logistics corridor.
