It is a 20 g capacity / 0.001 g division model. At that range the reading drifts with air flow and temperature — we ship a 20 g calibration weight and a one-page settling guide with every unit.
200 pcs for stock housing and stock colour. 500 pcs if you change colour or packaging. 1,000 pcs for a private mold.
We send the existing report for that model, or arrange testing under your brand if the model differs. Testing cost is quoted separately.
Tooling investment, mold ownership and exclusivity are defined in the project agreement before tooling starts. See our OEM/ODM process page.
