The ZONESUN ZS-MD818 combines metal detection, dynamic checkweighing and automatic rejection in one continuous inspection system. Packaged products are checked for ferrous, non-ferrous and stainless-steel contaminants, weighed against preset tolerances and automatically rejected when they fail either inspection.
Key Features
- Integrated metal detection, dynamic weighing and automatic rejection
- Separate touchscreen checkweigher control and button-type metal detector controller
- Detects ferrous, copper and stainless-steel contaminants
- Up to 80 products/min under compatible operating conditions
- Stores up to 100 product presets
- SUS304 stainless-steel construction

Touchscreen Control Panel
Allows operators to set target weight, tolerance limits and operating parameters while monitoring inspection results and machine status in real time.
Button-Type Metal Detector Controller
Allows operators to adjust metal-detection parameters and sensitivity through a straightforward button-operated interface.
Metal Detector
Detects ferrous, non-ferrous and stainless-steel contaminants as products pass through the inspection tunnel.
Dynamic Weighing Conveyor
Measures product weight during continuous conveying and compares each product with the preset acceptable weight range.
Automatic Reject System
Automatically removes products containing detected metal contaminants or falling outside the preset weight range, while qualified products continue downstream.
