Serving Rochester, MN
Rochester is the largest city in Olmsted County and the third most populous city in Minnesota, holding 121,395 of the county 162,847 residents at the 2020 Census. Its technical base is concentrated in clinical and biomedical work, municipally operated utilities, and EPA-regulated food processing and metal fabrication plants in the northwest industrial corridor. Mayo Clinic Hospital Rochester, a CMS-certified acute care hospital at 1216 Second Street Southwest, anchors that base, and FDA-registered medical device establishments operate at verified addresses elsewhere inside the city limits. Rochester International Airport, verified inside the city limits at 7600 Helgerson Drive SW and owned by the City of Rochester, operates an air traffic control tower with instrument landing systems on runways 13 and 31 and a co-located VOR/DME. Rochester Public Utilities, the municipally owned electric and water utility, works from its service center at 4000 East River Road NE and is replacing electric and water meters across the community under a multi-year advanced metering project. The city Water Reclamation Plant at 301 37th Street NW treats an average of 13 million gallons per day and runs an industrial pretreatment program built on permitting, inspection, and periodic sampling. Community Behavioral Health Hospital Rochester, a state-operated CMS-certified facility at 251 Wood Lake Drive SE, along with Rochester Community and Technical College at 851 30th Avenue SE and University of Minnesota Rochester at 111 South Broadway, adds clinical and teaching laboratory instrumentation to that mix. Work of this kind rests on temperature and humidity, pressure and vacuum, flow, mass and balance, electrical, torque, and dimensional measurement, each requiring documented traceability to national standards. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Rochester sits outside our Mid-Atlantic pickup radius, we serve Olmsted 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.
