Description
The ZONESUN ZS-MD818 / ZS-MD910K Checkweigher & Metal Detector combines dynamic weight inspection and inline metal detection in one conveyor system. Products are weighed during conveying and inspected for detectable ferrous, non-ferrous and stainless-steel contaminants before nonconforming items are removed by the push-rod rejection mechanism.
Two versions are available: ZS-MD818 with button-operated controls and ZS-MD910K with an LCD screen and data-copy function.

Performance note: The original parameter values above are retained unchanged. Actual weighing accuracy, metal-detection sensitivity and line speed depend on product size, packaging material, product effect, environment, conveyor stability and calibration.
Checkweigher Control
Operators can set target weight and tolerance limits and monitor dynamic weighing results.
Metal Detector Controller
Detection settings can be adjusted according to the product and required sensitivity.
Metal Detection Tunnel
Inspects products for detectable ferrous, non-ferrous and stainless-steel contaminants.
Dynamic Weighing Conveyor
Each product is weighed during continuous conveying and compared with the preset acceptable range.
Automatic Reject System
Nonconforming products are removed by the configured push-rod rejection mechanism.
Why Combine Checkweighing & Metal Detection?
The checkweigher verifies product weight while the metal detector checks for detectable metal contamination. Combining both functions reduces separate conveyor stages and centralizes rejection of nonconforming products.

Frequently Asked Questions
Can it detect metal through every package?
No. Packaging material and product characteristics can affect detection; metalized packaging requires separate evaluation.
Is ±0.3g to ±1g guaranteed for every product?
No. It is the original weighing-accuracy specification; actual results depend on the application.
What is the difference between ZS-MD818 and ZS-MD910K?
The page offers a button-control ZS-MD818 version and an LCD-screen ZS-MD910K version with data-copy functionality.
