Calibration Program
The CPS Calibration Program
The short version: every instrument we calibrate is enrolled in the program automatically, at no charge — whether you ship it to our shop or we calibrate it on-site at your facility. We track its due date, email you 30 days before it falls out of calibration, keep you posted at every step while it's with us, and every calibration finishes with a full certificate and a fresh due-date sticker on the unit. Staying compliant stops being a date somebody has to remember.
Most calibration shops hand back a certificate and send you on your way — and the next due date becomes your problem to track on a spreadsheet, a whiteboard, or a sticker nobody reads until it's overdue. We built the program around the calibration itself: the tracking, the reminders, the status updates, and the paperwork an auditor actually wants to see. It runs on our own calibration software, and it's included with every calibration we do.
Every Calibration Includes
One tier. No upsells. In-house or on-site, every calibration includes:
Ship them inFrom anywhere in the U.S. — box them up, write the RMA number on the box, send them to Rockwood, TN. 
We come to youFleets of 10+ instruments: our technician calibrates everything at your facility. No packing, no downtime. 
Fixed systems tooWall-mounted detectors and fixed points are enrolled and tracked the same way as your portables.How the Program Works
Four steps the first time. After that, it mostly runs itself.
Get your RMA number
A two-minute online form with your instrument details. Your RMA number arrives by email with instructions.
Send or bring your detectors
Ship to Rockwood, TN, drop off in person, or — for fleets of 10+ — we come to you. Every unit is logged in with its serial number and due date.
We calibrate every channel
Every sensor bump-tested, calibrated, and verified. Alarms checked. Sensors and batteries health-checked. You’re emailed as the work moves.
Back to work — and tracked
Certificates land in your inbox, fresh due-date stickers go on the units, and everything ships home. Thirty days before the next due date, we remind you.
What Your Certificate Proves
Hand it to your safety manager, your auditor, or OSHA. One certificate tier — every certificate documents the full job:
- As-found & as-left readingsEvery channel, before and after adjustment — not just a pass stamp
- NIST-traceable gas lot numbersThe exact calibration gas used, recorded on the certificate
- Certificate of Analysis linksClickable CoA for each gas lot — no QR code or camera needed
- Measurement uncertaintyStated on the certificate, the way an auditor expects to see it
- Pass/fail vs. manufacturer specsJudged against the instrument maker’s tolerances, not ours
- Next recommended due dateThe date the program tracks and reminds you about
Our lab quality system is being built around ISO/IEC 17025:2017, and our procedures and documentation structured to it as we work toward accreditation.
Program & Calibration Pricing
The program itself is free — it comes with the calibration. In-house calibration rates are flat and published:

| Single-gas meters | $55.00 | In-house calibration with standard sensors |
| 4 & 5 gas meters | $90.00 | In-house calibration with standard sensors, PID combos included |
| Sensor replacement | +$20.00 | Additional charge plus the cost of the sensor — always quoted and approved by phone first |
| Other repairs | $75.00/hr | Billed in half-hour increments plus the cost of parts |
| Declined repairs / unrepairable units | $45.00 | Shipping and evaluation fee — waived if you choose not to have the unit returned |
Turnaround & on-site work
Return shipping on ship-in work is the customer’s cost — send on your own carrier account, or we’ll bill the return freight with the calibration. See in-house calibrations and on-site calibration for the full service pages.
Frequently Asked Questions
Does the calibration program cost extra?
No. Enrollment is automatic and free with every calibration we perform — due-date tracking, the 30-day reminder emails, status updates, the QR due-date sticker, and your fleet page are all included. You pay for calibrations and any repairs you approve, nothing for the program itself.
How do the due-date reminders work?
Every enrolled instrument carries its next due date in our system. Thirty days before it falls out of calibration, we email you the unit, its serial number, and its due date — one email covering everything coming due, early enough to schedule around your work instead of scrambling after an audit finding.
What does the QR sticker on my detector do?
Each calibrated unit leaves with a sticker showing its next due date and a QR code. Anyone — a supervisor, a safety manager, an inspector — can scan it with a phone and see that instrument’s live certificate, plus every past certificate we’ve issued for it.
What happens if a sensor fails during calibration?
We call you before doing anything about it — that’s the call-first promise. You’ll get the finding, the replacement price (sensor replacement is a $20 labor charge plus the cost of the sensor), and your options. Nothing is replaced or billed without your approval.
We have instruments at several locations. Can the program handle that?
Yes. Units are tracked by location as well as by company, so each site can see its own fleet, due dates, and certificates — and reminders can go to the people who run each location.
Which brands do you calibrate?
We calibrate portable and fixed gas detectors from 30+ brands — including RKI, MSA, Honeywell BW, Dräger, Industrial Scientific, RAE Systems, Crowcon, Senko, SENSIT, and Gas Clip — whether or not you bought them from us. If it measures gas, ask us.
How fast is turnaround?
Standard in-house turnaround is 3–5 business days from arrival. You’ll get an email when your instruments arrive, when they’re on the bench, when they’re calibrated, and when they ship home — certificates attached.
Are fixed gas detectors covered by the program?
Yes. Fixed points we calibrate — on-site, or by shipping us the heads and controllers — are enrolled and tracked the same way, with certificates for every point. Most fixed systems need calibration about every six months, and the reminders keep that from slipping.
How do I get started?
