Description
The ZONESUN ZS-MD818 / ZS-MD910K is a fully automatic checkweigher and metal detector machine that combines dynamic weighing and inline metal detection in one integrated system. It supports weighing up to 3000g with weighing accuracy of ±0.3g to ±1g and speeds up to 80 pcs/min. Equipped with automatic push-rod rejection and SUS304 stainless steel construction, it is suitable for food, pharmaceutical, chemical, and other production lines requiring simultaneous weight compliance checking and metal contamination detection.
Two model options are available: the ZS-MD818 (button-operated control panel) and the ZS-MD910K (LCD screen with data copy function). Both models share the same core specifications and detection performance.

Why Choose the ZS-MD818 / ZS-MD910K?
✅ Combined Checkweighing & Metal Detection — Two Quality Checks in One Pass: Integrates dynamic weight checking and inline metal detection into one machine, allowing products to be simultaneously screened for weight compliance and metal contamination in a single pass — reducing line footprint, capital cost, and handling compared to running separate checkweigher and metal detector machines
✅ 80 pcs/Min High-Speed Inline Inspection — Production-Line Compatible: Supports up to 80 pieces per minute at conveyor speeds of 20–90 m/min, providing production-line-compatible inline checkweighing and metal detection speed for food, pharmaceutical, chemical, and consumer goods packaging lines without becoming a bottleneck
✅ ±0.3g–±1g Weighing Accuracy — Reliable Weight Compliance Checking: High-speed A/D sampling controller delivers ±0.3g to ±1g dynamic weighing accuracy for products up to 3000g, supporting reliable over/under weight detection and net content compliance checking for food and pharmaceutical packaging regulations
✅ Fe ≥1.0mm / Cu ≥1.5mm / SUS ≥2.0mm — Multi-Metal Detection Sensitivity: 150×210mm detection channel identifies ferrous metal (Fe ≥1.0mm), non-ferrous metal (Cu ≥1.5mm), and stainless steel (SUS ≥2.0mm) contaminants inline, providing broad metal contamination detection coverage for food safety, pharmaceutical GMP, and product quality requirements
✅ Automatic Push-Rod Rejection — Non-Conforming Product Removal Without Stopping Line: Push-rod rejection system automatically diverts out-of-weight or metal-contaminated products from the conveyor without stopping production, maintaining continuous throughput while keeping non-conforming items separated from accepted product output
✅ 100 Preset Product Numbers — Quick Changeover for Multiple SKUs: Stores up to 100 product presets in the control system, allowing operators to quickly recall saved weight thresholds and detection parameters for different products without re-entering settings — reducing changeover time on multi-SKU production lines
✅ Two Model Options — Button Panel or LCD Screen with Data Copy: ZS-MD818 provides straightforward button-operated control for standard production use; ZS-MD910K adds an LCD touchscreen interface with data copy function for operations requiring production record management, data export, or traceability documentation
✅ SUS304 Stainless Steel — Durable Hygienic Construction: Full SUS304 stainless steel machine body provides durable, corrosion-resistant, washdown-compatible construction suitable for food processing, pharmaceutical, and chemical production environments requiring hygienic equipment surfaces and easy cleaning
Ideal Applications
Food Packaging Weight & Metal Inspection: Inline checkweighing and metal detection for packaged food products including snacks, confectionery, frozen food, ready meals, meat products, seafood, and other food packaging lines requiring simultaneous net content weight compliance and metal contamination screening at up to 80 pcs/min
Pharmaceutical & Nutraceutical Product Inspection: Dynamic weight checking and metal detection for pharmaceutical tablets, capsules, blister packs, nutraceutical pouches, and other health product packaging requiring GMP-compatible inline weight compliance and metal contamination inspection with SUS304 hygienic construction
Chemical & Industrial Product Inspection: Inline checkweighing and metal detection for chemical product pouches, industrial component bags, hardware packaging, and other non-food industrial products requiring simultaneous weight and metal contamination quality control on automated production and packaging lines
Consumer Goods & Cosmetics Packaging Inspection: Automatic weight and metal screening for cosmetic product boxes, consumer goods packages, personal care product packaging, and other retail consumer product lines requiring consistent weight compliance and metal contaminant rejection for finished goods quality assurance
Multi-SKU Production Lines Requiring Quick Changeover: 100-preset product memory allows food, pharmaceutical, and consumer goods manufacturers running multiple product SKUs on shared packaging lines to quickly switch between saved product parameters, making the ZS-MD818/ZS-MD910K practical for flexible production environments with frequent product changeovers
