About Radius250

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.

What we do

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.

How we work

What you can count on.

V-01

Traceable, always

Every reading ties back to a standard and a calibrated reference. No exceptions, no hand-waving.

V-02

Audit-ready by default

Our deliverable isn't a sticker — it's documentation built to be opened in front of an inspector.

V-03

On the clock

Controlled environments can't sit idle. We schedule tight and turn reports around in a day.

V-04

Rooted, then routed

Local enough to show up fast, equipped to travel well past the 250-mile core radius.
