Medical Scale Calibration: What Clinics Need and What It Costs
Medical scale calibration for a physician scale at MNM Scales is $495.00 with an in-house certificate or $995.00 with a NIST-traceable certificate, by mail nationwide or on-site at your clinic anywhere in the Houston area.
Short answer: we calibrate physician, wheelchair and infant scales in our Cypress, TX shop or on-site at your clinic. Price follows the scale’s maximum capacity: most physician and wheelchair scales (550–1,000 lb) are over 150 kg, so in-house calibration with a certificate is $495.00 and NIST calibration with a NIST-traceable certificate is $995.00. Infant and pediatric scales between 6.2 and 35 kg are $250.00 in-house or $595.00 NIST. On-site service is $295 plus $2 per mile round trip per visit, with each scale priced on top. Mail-in calibration usually takes 1–3 business days after we receive the scale.

A patient’s weight drives dosing, nutrition and follow-up decisions, so clinics need to know their scales read true. This guide covers how medical scale calibration works, how often clinics usually schedule it, what a check involves, what to keep on file, and what it costs at MNM Scales for each type of scale.
Medical scale calibration prices by scale type
| Scale type | Typical capacity | Calibration tier | In-house certificate | NIST-traceable certificate |
|---|---|---|---|---|
| Physician (column, eye-level or handrail) | 550–660 lb (250–300 kg) | Over 150 kg | $495.00 | $995.00 |
| Wheelchair and bariatric platform | up to 1,000 lb | Over 150 kg | $495.00 | $995.00 |
| Infant and pediatric (6.2–35 kg) | about 14–77 lb | 6.2–35 kg | $250.00 | $595.00 |
| On-site service call | Houston area | Per visit | $295 plus $2 per mile round trip | $295 plus $2 per mile round trip |
In-house calibration comes with our certificate, using NIST-tested weights. NIST calibration comes with a NIST-traceable certificate, which some accreditation reviews and hospital systems ask for. If you are not sure which certificate your facility needs, ask your compliance lead or get a quote and we will help you choose.
How often clinics calibrate their scales
Most clinics schedule a certified calibration at least once a year, and again whenever a scale is moved, dropped, repaired or starts reading differently from another scale in the office. Busy practices, urgent care centers and dialysis or weight-management programs often add a quick in-house check with a known weight weekly or monthly between calibrations. If your manufacturer’s manual, accreditation body or facility policy sets an interval, follow that one. Our guide to how often a scale should be calibrated covers intervals by use.
What a medical scale calibration check looks like
- Inspect and level. We check the platform, feet, handrail or column, cables and display, and level the scale where it is used.
- Zero. The empty scale must return to zero and hold it.
- Span across the range. Certified weights are placed in steps up the range the scale is used for, and readings are compared with the known values.
- Corner (eccentric) test. The same weight is placed at each corner of the platform; a physician or wheelchair scale should read the same wherever the patient stands or the chair rolls.
- Repeatability. The same load is placed several times to confirm the reading comes back the same.
- Adjust and certify. If readings are out, the scale is adjusted and rechecked, and the as-found and as-left results go on the certificate.
What to keep on file
- The calibration certificate for each scale, with the serial number, date, and as-found and as-left readings.
- A simple check log between calibrations: date, test weight used, reading, and initials.
- The date the scale was moved, repaired or replaced, so the next calibration can be scheduled from it.
- The type of certificate your facility requires (in-house or NIST-traceable).
When a medical scale needs repair instead
If a scale will not hold zero, drifts while a patient stands still, shows an error code, reads differently at each corner, or has a damaged cable, handrail or platform, calibration alone may not fix it. We repair all brands and types of scales in our shop or on-site through our Houston scale repair service, and calibrate after the repair. Our guides to scales that will not zero or drift and scale error codes cover common causes.

Calibration, repair and rentals
Mail-in calibration is available nationwide by mail, for in-house and NIST certificates, and usually takes 1–3 business days after we receive the scale; see mail-in scale calibration. On-site calibration covers medical offices, clinics and care facilities across Houston and its suburbs at $295 plus $2 per mile round trip per visit; see scale calibration in Houston and our NIST calibration certificate page. Need a scale while yours is in the shop? We rent scales in the Houston area; call or get a quote.
Notes from our Cypress, TX shop
- Calibrate where the scale lives. A physician scale moved from one exam room to another should be leveled and checked again.
- Book every scale in the office on one visit. The service call is charged once per visit, so one trip covers the physician, infant and wheelchair scales together.
- Match the certificate to your policy before you book. In-house and NIST-traceable certificates are priced differently.
- Write down the serial numbers. Certificates are issued per scale, and the serial number is how auditors match them.
