We make compliance measurable.
Rooted Locally. Trusted Globally. Radius250 exists for the facilities where a number has to be right — cleanrooms, cabinets, cold storage, and the instruments that judge them. We test, calibrate, and validate, then hand you the evidence to prove it.
Why “Radius250”?
The name is the operating model. We're rooted in Harrisburg, Pennsylvania, with a 250-mile core radius we can serve fast and predictably — and a reach that extends well beyond it when the work calls for it.
That blend — local responsiveness, national-grade rigor — is the whole point. Rooted locally, trusted globally.
Three disciplines, one partner.
Certification
We confirm controlled environments meet the standard — cleanrooms, cabinets, hoods, and barriers tested to NSF, ISO, USP, and ASHRAE.
Calibration
We make instruments tell the truth — NIST-traceable calibration of gauges, probes, counters, and temperature equipment.
Validation
We prove the process holds — IQ/OQ/PQ, smoke studies, and documented evidence built to survive an audit.
What you can count on.
Traceable, always
Every reading ties back to a standard and a calibrated reference. No exceptions, no hand-waving.
Audit-ready by default
Our deliverable isn't a sticker — it's documentation built to be opened in front of an inspector.
On the clock
Controlled environments can't sit idle. We schedule tight and turn reports around in a day.
Rooted, then routed
Local enough to show up fast, equipped to travel well past the 250-mile core radius.
