What is a Checkweigher / Weight checker?

A weight checker, also known as a checkweigher, is an automated inspection device used on production lines to measure the weight of products in real time. If a product does not meet the preset weight standards, it is automatically rejected from the line. These systems are widely used in industries such as food, pharmaceuticals, cosmetics, and manufacturing—particularly in the final packaging or pre-shipment stages.

When a product passes over the built-in high-precision scale on a conveyor, the system quickly measures its weight and compares it against the target range. Overweight or underweight items are rejected using mechanisms like air jets or diverter arms. In the food industry, checkweighers help ensure fair product quantities for consumers and assist with compliance to regulations such as legal metrology laws or HACCP standards. Additionally, the recorded measurement data supports traceability and production analysis.

Using a checkweigher improves product consistency, reduces waste, and strengthens quality assurance.
