Scale Calibration Company in Houston, TX Since 1992
MNM Scales has sold, serviced and calibrated scales for over 30 years, and our Cypress shop is where most Houston-area jobs start. For weighing instrument calibration in Houston, all we need is the brand, model, maximum capacity and number of units. From that we quote a per-scale price from the table below, whether the scale is a 0.1 mg lab balance, a shipping bench scale or a 5,000 lb floor scale.
What happens during a calibration:
- We check that the scale is level, clean and warmed up, and that the platform or pan moves freely.
- We test it with calibration weights at several points across its range, including near full capacity.
- If a reading is outside tolerance, we adjust the scale and test it again.
- You receive a calibration certificate: in-house with NIST-tested weights, or NIST calibration with a NIST-traceable certificate.
- Legal-for-trade scales in Texas are placed in service with the RWM-780 service report.
Scale Calibration Services in Houston
In-house calibration with certificate
We test and adjust your scale in our Cypress shop with NIST-tested weights and return it with a calibration certificate. It suits shipping, production, retail, kitchens and general testing.
NIST calibration with NIST-traceable certificate
This is a full calibration documented on a NIST-traceable certificate, so labs, pharmacies, QC programs and auditors can trace every reading back to national standards. Our NIST calibration services page shows what the certificate records, the NIST prices by capacity and how to order by mail.
On-site scale calibration in Houston
Our technicians bring NIST-tested weights to labs, pharmacies, medical offices, plants, warehouses and stores. That includes our own heavy test weights for floor and crane scales, so there is nothing for you to provide. The on-site service call is $295 plus $2 per mile, round trip, charged once per visit, and each scale is then calibrated at the per-scale rates below. Bringing several scales together on one visit spreads that call across all of them. See what to expect from on-site scale calibration in Houston. We also install and calibrate forklift and loader scales on-site; for plants and warehouses, see industrial scale calibration in Houston.
In-shop, pre-sale and mail-in calibration
You can drop off at our Cypress shop at 21249 FM 529 Rd (visits by appointment), add calibration to a new scale order so it arrives ready to use (or pick the order up at the shop by appointment), or mail your scale in, wherever you bought it. Mail-in calibration is available nationwide, with in-house calibration and NIST calibration. Calibration is usually finished within 1-3 business days after we receive the scale. See mail-in scale calibration to send yours.
Legal-for-trade scales in Texas
MNM Scales is a TDA-licensed service company, and our TDA-registered technicians place commercial scales into service and handle the paperwork, including the RWM-780 service report and the RWM-700 device registration application. A scale used to sell or charge by weight must meet NIST Handbook 44 and be suitable for its use, usually an NTEP-approved model, and be placed into service. Not sure whether yours counts? Try our free legal-for-trade scale checker. Read more about legal-for-trade scale calibration in Texas. Shopping for a trade-approved scale? See our NTEP legal-for-trade scales.
Calibration Prices
Prices are per scale and based on the scale’s maximum capacity. For dual-range models, use the highest range. A capacity exactly at a limit stays in the lower tier. Rough conversions: 5 lb ≈ 2.3 kg, 75 lb ≈ 34 kg, 300 lb ≈ 136 kg, 500 lb ≈ 227 kg.
| Max capacity | Typical equipment | In-house calibration with certificate | NIST calibration with NIST-traceable certificate |
|---|---|---|---|
| Up to 2.2 kg | Analytical, precision and jewelry balances, small crane scales | $95 | $395 |
| Over 2.2 to 6.2 kg | 3-6 kg precision and toploading balances | $195 | $495 |
| Over 6.2 to 35 kg | Bench, counting, washdown and shipping scales | $250 | $595 |

Planning an on-site visit in Houston
- Group your scales. One service call covers every scale at the same address on that visit, so list them all when you book.
- Send the details. Brand, model, maximum capacity and quantity for each scale, plus which ones sell or charge by weight so we bring the TDA paperwork.
- Clear access. Have each scale reachable, empty and powered on. For floor and crane scales our technicians bring their own heavy test weights.
- Pick a certificate. In-house calibration with NIST-tested weights for everyday use, or NIST calibration with a NIST-traceable certificate for labs, pharmacies and audits.
Who We Calibrate For
Here are typical calibration jobs we handle around Houston:
We calibrate analytical and precision balances, bench, counting and washdown scales, crane and hanging scales, and floor and industrial scales.
Repairs, Parts and Rentals
Scale repair and calibration come from the same team. We provide scale repair in Houston for all brands and types of scales, in our shop or on-site. Send us the brand, model and type of scale, and we’ll quote the repair; timing depends on the scale and what it needs. We stock load cells, indicators, calibration weights and parts, and we rent out all types of scales too (see scale rentals in Houston). The problems our technicians see most are scales left in calibration mode or with the wrong settings turned on by accident, load cells that went bad after heavy use, and cut cables, so tell us what the scale is doing when you call.
Emergency and same-day service
If a scale goes down, call (832) 290-3120 any time for same-day availability in the Houston area. Emergency calls are quoted per call.

Our technicians bring their own NIST-tested weights, including heavy test weights for floor and crane scales, so there is nothing extra to arrange.

Yes. Add the in-house or NIST calibration for each scale’s capacity tier to your cart, one per scale. For on-site service, call (832) 290-3120 or request service online.
Is a local scale company better than a national calibration company?
For most Houston businesses, a local company keeps calibration simple. MNM Scales has served the area since 1992 from our Cypress shop, our TDA-registered technicians bring their own test weights to your site, and we answer the phone 24/7 for scheduling.
