Serving St. Charles, MO
St. Charles sits on the Missouri River in eastern Missouri and holds the St. Charles County government offices at 201 N. Second Street, placing county administration and the First Missouri State Capitol State Historic Site, the first seat of the state government, inside the same city limits. The city technical base is concentrated in metalworking, specialty fabrication, regulated healthcare, municipal treatment and instrument manufacturing rather than in any single sector. Trinity Products at 3251 Harry S Truman Boulevard works in iron and steel pipe and tube production, and Craftsmen Industries runs sheet metal and specialty vehicle fabrication at 3101 Elm Point Industrial Drive and 3800 West Clay Street. BC Group International, Inc. at 3081 Elm Point Industrial Drive is an FDA-registered medical device establishment, which places device-level test and measurement work inside the city, and AssayPro at 3400 Harry S Truman Boulevard runs laboratory assay work at a site recorded in both EPA facility data and federal award records for the Department of Veterans Affairs. SSM Health St. Joseph Hospital in St. Charles at 300 First Capitol Drive is an acute care hospital and a state-designated Level II STEMI center. The city also runs the Missouri River wastewater facility at 2500 North Main Street under NPDES permit MO0000002918300083, rated at 7.54 million gallons per day, alongside an industrial pretreatment program that holds dischargers to measured limits. Across those sites the recurring measurement disciplines are dimensional, pressure, temperature, torque, mass, electrical and flow, each carrying documented uncertainty and traceability back to national standards. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because St. Charles sits outside our Mid-Atlantic pickup radius, we serve St. Charles County through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Each calibration is performed against documented procedures, traced through NIST, and accompanied by an audit-ready certificate that supports AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.
