MNM Scales is an authorized OHAUS dealer stocking NTEP gold scales and legal-for-trade cannabis scales for jewelers, pawn shops, coin and bullion dealers, gold buyers and dispensaries. The OHAUS Scout SJX/E series leads the range, with Valor 4000 bench scales and Pioneer and Adventure analytical balances alongside. As one of the largest scale distributors in Texas, we ship every scale free, and our Cypress, TX shop can calibrate it before it leaves.
What to look for in a gold scale
When you buy or sell gold, silver, gemstones or cannabis by weight, the scale must be NTEP approved for that use. Check three things on the product page:
- Accuracy class. Class II is the class for precious metals and gemstones. Class III suits larger, coarser weighing.
- Certified division (e). The SJX1502N/E reads 0.01 g and is certified at e = 0.1 g, while the SJX323N/E is certified at e = 0.01 g.
- Units. Scout SJX/E models weigh in carats, pennyweight, troy ounces and grains, the units your customers expect.

Choosing the right OHAUS gold scale
Jewelry and gold buying counters
The SJX1502N/E is the go-to Class II scale for scrap gold, chains and rings up to 1,500 g. For diamonds and loose stones, the SJX323N/E gives a finer 0.01 g certified division.
Coin, bullion and silver
Silver and coin dealers often weigh larger lots. The SJX6201N/E handles up to 6,200 g, and the Valor 4000 bench scales handle boxes and bags.
Cannabis dispensaries
Dispensaries selling by the gram usually choose a Class II scale certified at 0.01 g. Compare options in our best scale for a cannabis dispensary guide, and see Class II balances such as the A&D FX-200iN in our NTEP precision balances.
Assay and testing
For karat testing and lab checks at 0.1 mg, the OHAUS Pioneer PX124 and Adventure AX124 bring internal calibration to the bench.
Calibration and Texas placed-in-service
Every scale on this page can ship calibrated from our Cypress, TX shop. Calibration is priced by the scale’s maximum capacity:
| Scale maximum capacity |
In-house calibration with NIST-tested weights |
NIST calibration with NIST-traceable certificate |
| Up to 2.2 kg (4.85 lb) |
$95 |
$395 |
| 2.2–6.2 kg (4.85–13.7 lb) |
$195 |
$495 |
| 6.2–35 kg (13.7–77 lb) |
$250 |
$595 |
A scale whose capacity is exactly at a tier limit uses the lower tier.
The SJX1502N/E falls in the up to 2.2 kg tier, and the SJX6201N/E falls in the 2.2–6.2 kg tier. Calibration usually takes 1–3 business days after we receive the scale, and our mail-in scale calibration service covers scales bought anywhere. In Texas, a commercial scale must be placed into service and registered with the Texas Department of Agriculture. MNM Scales is TDA licensed with registered technicians for all scale classes, and our technicians handle the RWM-780 and RWM-700 paperwork for you. See TDA scale certification.
