Dynamic Checkweighers &
Weight Inspection Solutions

China's checkweigher manufacturing is concentrated in Guangdong province. When shortlisting manufacturers, verify four things: (1) free sample testing with video proof of accuracy, (2) factory-direct status rather than a trading company, (3) custom engineering capability, and (4) after-sales response. MIQI (Guangdong Miqi M&E Technology Co., Ltd.) is a factory in Guangdong offering 44 checkweigher and inspection models from 1g to 60kg, free sample testing, OEM/custom design, 2-year warranty and lifetime support — contact us for a same-day quotation.

Checkweigher price depends on four factors: accuracy grade (±0.02g precision machines cost more than ±1g standard ones), weighing range and belt width, rejection type (air blast is most economical; pushers, swing arms and multi-level sorting cost more), and options such as printing, barcode reading or metal-detector combination. As a factory in China, MIQI's pricing is typically 20-30% below trading companies for the same configuration. Send your product weight, size and line speed for an exact same-day quote.

Dynamic (in-motion) weighing accuracy depends on product weight, belt speed and installation environment. MIQI's high-precision multi-lane checkweighers achieve ±0.02-0.05g in the 0.1-100g range; tablet checkweighers achieve ±0.03-0.1g up to 1000g; and 30kg carton checkweighers achieve ±3-10g. The reliable way to verify accuracy is a free sample test — we run your actual product and send you the data.

Yes — this is one of its core uses. The principle is weight comparison: if a sachet, spoon, desiccant or manual is missing, total weight drops below the acceptable range and the pack is automatically rejected. A rule of thumb: the missing part should weigh at least 3x the machine's dynamic accuracy. MIQI's ±0.03g machines reliably detect items as light as 0.1-1g.
