Description
The ZONESUN ZS-MD1010 Automatic Checkweigher with Rejection is designed for continuous in-motion weight inspection of packaged products. Each item is weighed on the conveyor, compared with the preset acceptable range and automatically rejected when it falls outside the configured tolerance.
The standard single-weighing range is ≤200g, with a listed weighing accuracy of ±0.1g and maximum speed of 150 pcs/min. Actual dynamic weighing performance depends on product size, spacing, conveyor vibration, environmental conditions and calibration.

Performance note: The original parameter values above are retained unchanged. ±0.1g and 150 pcs/min are machine specifications rather than guaranteed results for every package. Product weight, dimensions, spacing, conveyor conditions, vibration and reject timing can affect actual performance.
Touchscreen Control
Operators can set target weight, upper/lower tolerances and operating parameters while monitoring weighing results.
Three-Color Weight Indicator
Provides visual status feedback for acceptable, underweight and overweight results according to the configured thresholds.
Dynamic Weighing System
Measures each product during conveyor transport without requiring the normal inspection cycle to stop.
Automatic Reject System
Products outside the preset weight tolerance are removed automatically using the configured pneumatic reject mechanism.
Compact Stainless-Steel Frame
The compact structure is intended for inline integration with compatible filling, sealing, labeling and cartoning equipment.
Best-Suited Applications
Suitable for compatible small packaged products where an inline weight check can help identify missing, underfilled, overfilled or otherwise out-of-tolerance units.
Needs separate evaluation: products over 200g, unstable or rolling packages, products larger than the specified conveyor area, highly vibrating production environments or packages requiring a different reject mechanism.
Checkweigher vs Static Scale
| Dynamic Checkweigher | Weighs products while they move through a production line and can automatically reject out-of-tolerance units. |
|---|---|
| Static Scale | Measures a stationary item and is generally used for manual or offline weighing rather than continuous inline inspection. |

Frequently Asked Questions
Is ±0.1g guaranteed at 150 pcs/min?
No. Both values are original machine specifications; achievable accuracy at a given speed depends on the actual package and line conditions.
Can it reject both underweight and overweight products?
Yes. Products outside the configured acceptable weight range can be rejected automatically.
Can it be installed after a filling machine?
Yes, provided conveyor height, product spacing and line speed are coordinated.
