Serving St. Paul, MN
St. Paul is the Ramsey County seat and the center of Minnesota state government, which concentrates public laboratories, regulated healthcare, utility infrastructure, and light manufacturing inside one city boundary. The Minnesota Department of Agriculture and Minnesota Department of Health laboratory building at 601 Robert Street North and the Bureau of Criminal Apprehension forensic science laboratory at 1430 Maryland Avenue East both sit within city limits and run analytical work that depends on documented measurement traceability. Regions Hospital at 640 Jackson Street and Gillette Children’s Specialty Hospital at 200 University Avenue East are Medicare-certified hospitals in the city, where clinical engineering and facilities equipment is held to recorded tolerances. Utility and environmental infrastructure is inside the boundary as well: the Metropolitan Council Metropolitan Wastewater Treatment Plant at 2400 Childs Road operates under NPDES permit MN0029815, and the Xcel Energy High Bridge Combined Cycle Plant at 155 Randolph Avenue operates under NPDES permit MN0000884. St. Paul Downtown Airport, also known as Holman Field and assigned FAA identifier STP, lies inside the city on the Mississippi River and operates an air traffic control tower, instrument landing systems on Runways 14 and 32, and an automated surface observing system. On the manufacturing side, Viking Drill and Tool at 355 South State Street and Pier Foundry and Pattern Shop at 51 South State Street are registered manufacturing sites in the EPA Facility Registry Service at in-city addresses, and Saint Paul College at 235 Marshall Avenue and Metropolitan State University at 700 East Seventh Street train technical staff a short distance from them. A mix of that kind draws on dimensional, electrical, temperature, pressure, torque, mass, flow, and humidity measurement, each carrying its own uncertainty budget and recall interval. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because St. Paul sits outside our Mid-Atlantic pickup radius, we serve Ramsey 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.

Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.
Onsite Calibration:

Calibration is performed in a controlled environment at your site on a scheduled appointment, with the same accreditation, NIST traceability, and documentation as in-lab service.
