Checkweighers
Checkweighers weigh every pack as it moves along the line and reject any that fall outside the target range, controlling giveaway while keeping fills legal. As part of the inspection and quality control stage on a food processing line, they sit downstream of filling and packing to catch underweight and overweight packs before they reach the case. Belt speed, weighing accuracy at that speed and the reject method decide whether a machine suits your product and rate. A gentle reject matters for fragile or unstable packs. New and used checkweighers appear here from verified sellers, with speed, weight range and condition stated on each listing.

Checkweigher Types
Checkweighers vary in weight range, line speed and how they reject failing packs. The main types are below.
High speed checkweighers
These machines weigh packs at fast line rates for high volume production. Accurate weighing at speed is what separates them from slower units.
Heavy duty checkweighers
Built for larger cases and bulk packs, these units handle higher weight ranges. Robust construction and stronger reject mechanisms suit heavier products.
Combination checkweighers
Some units pair weighing with metal detection or other checks in one frame. This saves line space and simplifies a combined weight and contamination check.
Gentle reject checkweighers
For fragile or unstable packs, gentle reject methods remove failing product without damage or spillage. Match the reject type to the pack format to avoid line disruption.

Por qué elegir Machinery Masters
Solo vendedores verificados
Cada vendedor se verifica antes de que se publique un solo anuncio. Machinery Masters también revisa la exactitud de los anuncios, para que los compradores puedan invertir con confianza en maquinaria de alto valor.
Alcance global
Los anuncios proceden de vendedores de toda Europa, Norteamérica y otros lugares. Ese alcance amplía las opciones más allá de cualquier red regional de distribuidores y, a menudo, es la única forma de encontrar modelos descatalogados en buen estado.
Opciones de financiación flexibles
Los anuncios que cumplen los requisitos ofrecen financiación a través de proveedores asociados. Las condiciones se muestran directamente en las páginas de producto correspondientes, repartiendo el coste en lugar de agotar el capital circulante de una sola vez.
Contacto directo con el vendedor
No hay ningún intermediario entre el comprador y el vendedor. Pregunte por el historial de mantenimiento, organice inspecciones y negocie directamente con la persona que realmente conoce la máquina.
Applications and Uses
These machines guard fill accuracy across food, beverage and consumer goods lines. The main settings follow.
Giveaway control
Catching overfilled packs stops product going out as free giveaway. Trimming that loss protects margin on every pack that runs.
Underfill and compliance checks
Rejecting underweight packs keeps fills within legal average weight rules. This protects the producer from compliance failures and customer complaints.
Missing component detection
A weight outside the target can flag a missing item or component in a pack. Catching these faults protects product quality and completeness.
Statistical process feedback
Weight data feeds back to filling equipment to keep the process centred. This tightens fill control and reduces variation over a run.
Benefits from Machinery Masters
The marketplace lists these units alongside the rest of the inspection and quality control line.
01
Speeds and weight classes side by side
High speed, heavy duty and combination units are grouped, so matching a machine to your rate and pack weight takes one search.
02
Second hand weighing, full margin protection
A serviced used checkweigher controls giveaway to the same standard as a new machine for far less outlay. Weight range, belt speed and condition sit on the listing so the saving is plain.
03
Watch the reject fire before buying
You deal with the seller directly, so ask to see the machine reject a failing pack at your line rate. That conversation also settles condition, service history and spares before you commit.
Frequently Asked Questions sobre Checkweighers
Ask for evidence it weighs accurately at your line speed using known check weights. Confirm the reject mechanism fires cleanly and the load cell and belt are in good order. A machine that drifts or misses rejects will not protect either your margin or your compliance.
The machine must weigh your pack accurately at your production rate in packs per minute. Confirm the weight range covers your product and the belt handles your pack size. A unit rated for a slower or lighter line will limit throughput and accuracy.
Reject methods range from air jets and pushers to drop and belt diverts, and the right one depends on pack weight and stability. Fragile or tall packs need a gentle reject to avoid damage or spillage. Match the reject type to your pack format before buying.
Combination units house a checkweigher and metal detector in one frame to save line space. This gives a single stage for both weight and contamination checks. If space is tight, a combined machine can be more practical than two separate units.
Listings come direct from the machine's owner, and you contact them to confirm accuracy, speed and condition. There is no intermediary in the conversation. That direct line lets you settle the technical detail before committing to the purchase.
