Range

Milligram jewelry scale models

The jewelry line is the precision half of our range — five models on our own boards, from 0.001 g milligram reading up to 1 kg. For 0.01 g general pocket scales, see the pocket scale line.

MM-810 also sits first on the pocket scale line — it is the one model that crosses both: milligram reading, 500 pcs entry MOQ.

FAQ

Buyers ask these four things

Is 0.001 g real, or marketing?

It is a 50 g capacity / 0.001 g division model. At that range the reading drifts with air flow and temperature — we ship a calibration weight and a one-page settling guide with every unit.

What is the real MOQ?

500 pcs for your logo on an existing mold (10–15 days). 1000-2000pcs for a new colour, packaging and manual (20–30 days). 3000-5000pcs for a private mold designed for you (90–110 days).

Can I get CE / RoHS for my model?

We send the existing report for that model, or arrange testing under your brand if the model differs. Testing cost is quoted separately.

Who owns the mold if I pay for it?

Tooling investment, mold ownership and exclusivity are defined in the project agreement before tooling starts. See our OEM/ODM process page.
