The X3 Series has been developed specifically for unpackaged, loose-flow, bulk products on conveyors. Both systems in the series can detect contaminants as small as 0.3 to 0.4 mm, depending on application and contaminant material, protecting equipment, preventing costly recalls, and supporting compliance with global safety standards. Typical applications include dried, fresh or frozen fruits and vegetables, nuts, pulses, root vegetables such as carrots and potatoes, confectionery, and cereals.

Reject options include a 30-nozzle air blast for pinpoint removal of contaminants in smaller products, or a 6-flap pusher reject for the removal of contamination in larger produce. With reject devices positioned above the product, they are less likely to become blocked or clogged with product debris, thereby maintaining performance and supporting hygienic handling, the company says. These targeted reject systems allow manufacturers to aim to minimize product waste and protect profitability.

In addition, the X3 Series has throughput rates of up to 5,000 kg per hour.

X13 X-ray Inspection System

The X13 combines detection with an affordable price point to provide a cost-effective gateway to advanced bulk inspection, adds Mettler Toledo. Equipped with HiGain+ detector technology and ContamPlus software, it aims to deliver sharp imaging and reliable detection of physical contaminants such as metal, glass, calcified bone, and stone in a large variety of bulk flow applications, regardless of consistency or format.

X53 Dual-Energy X-ray Inspection System

As the premium solution from the range, the X53 is engineered for manufacturers who handle the most complex bulk products and require exceptional accuracy, the company adds. Building on the performance of the X13, the X53 integrates HiGain+ DE (Dual Energy) detector technology and AMD (Advanced Material Discrimination) Pro software to deliver an additional layer of analytical intelligence. By processing two energy spectrums simultaneously, the X53 can differentiate between materials with similar densities such as bone and product, reportedly allowing it to detect challenging low-density contaminants that single-energy systems may miss.

The X53 also introduces enhanced traceability and automation features, including product validation routines, self-checking performance verification, and a fully lockable inspection tunnel for secure operation. These capabilities make it suitable for high-throughput or high-risk environments, where sensitivity, reliability, and compliance are critical.

Hygienic, operator-friendly design

Both X3 models feature front open conveyor access and tool-free removal of key components. Options such as belt scrapers, water-cleaning systems, and removable guide rails make sanitation faster and more effective, Metter Toledo says, while integrated cable management reduces clutter. Each system is available with a choice of ingress protection ratings up to IP69, providing flexibility to suit different hygiene standards and cleaning regimes.

Regulatory compliance

The X3 Series helps manufacturers inspect, protect, and comply with confidence by combining detection performance with digital transparency. Full connectivity to ProdX enables real-time monitoring, automated reporting, and long-term data storage, aligning with global regulatory priorities for traceability.
