Question 1

What is flowmeter calibration?

Accepted Answer

Calibration verifies that a medical gas flowmeter delivers the flow it indicates on its scale — typically in liters per minute (LPM). We compare the unit's readings against NIST-traceable reference standards across its full range and document the measured values on a calibration certificate.

Question 2

How often should a medical gas flowmeter be calibrated?

Accepted Answer

Manufacturers and most accreditation bodies recommend calibration at least annually. Facilities surveyed by Joint Commission, AAAHC, or state DOH should keep current calibration documentation on file for every clinical flowmeter — oxygen, nitrous oxide, air, and vacuum.

Question 3

What's the difference between calibration and repair?

Accepted Answer

Calibration ($450) is for flowmeters that already function correctly but need their accuracy verified and documented. Repair ($950) covers units that leak, drift, stick, or fail function tests and need internal service before calibration. If you're unsure, ship it as calibration — we'll contact you with a quote if repair is required.

Question 4

Which flowmeters do you calibrate?

Accepted Answer

We calibrate medical gas flowmeters from Western Medica, Precision Medical, Amico, Ohio Medical, Porter, Accutron, Matrx, GenTech, and most other major OEMs. This includes wall, cylinder, and Thorpe-tube flowmeters for oxygen, nitrous oxide, medical air, and vacuum.

Question 5

Do I get a calibration certificate?

Accepted Answer

Yes. Every unit ships back with a NIST-traceable calibration certificate listing the reference standards used, the measured values across the flow range, environmental conditions, and the technician of record. The certificate is accepted by Joint Commission, AAAHC, CMS, and state surveyors.

Question 6

How do I ship my flowmeters in?

Accepted Answer

Complete checkout online to generate an order number (e.g. MTS-01001), write that number on two sides of your shipping box, and ship to our calibration lab. You cover outbound shipping; we cover return shipping anywhere in the continental US.

Question 7

Do you calibrate dental flowmeters?

Accepted Answer

Yes — dental nitrous oxide/oxygen flowmeters are calibrated on the same NIST-traceable bench. If you specifically need dental flowmeter repair (not just calibration), see our Dental Flowmeter Repair & Calibration page for the $950 repair option.
