Checkweighers — every gram counts.

Dynamic weighing at full line speed: underweight packs are rejected, overweight giveaway is cut, and every batch is documented for EU average-weight (e-mark) compliance.

A checkweigher weighs each pack as it passes and rejects those outside tolerance. The commercial case is simple: 2 g of giveaway on a 200 g pack is 1% of your product cost, every day. The legal case is the EU 'e-mark' average-weight system (Directive 76/211/EEC), which requires statistical control of net contents — the checkweigher's batch reports are your evidence.

We supply Thermo Scientific Global VersaWeigh and Versa GP for general packaged goods, Versa Flex and Versa Rx for dry and pharmaceutical applications, Versa 8120 chain weighers up to 700 packs/min, Teorema for can lines, Frame 44 and Box series up to 50 kg, and Fortress Raptor checkweighers and caseweighers — including combination frames with metal detection. Installed, calibrated and OIML/MID-verified where required.

Typical applications

  • Flow-packed and tray-packed meat, cheese, bakery
  • Bottles, cups and cartons in dairy and beverage
  • Cans at up to 700 per minute
  • Cases, bags and sacks up to 50 kg
  • Pharmaceutical and cosmetic packs (Versa Rx)
  • Combination with metal detection or X-ray on one frame

FAQ

Frequently asked questions

What accuracy can a checkweigher achieve?

Typical standard deviation is ±0.1–0.5 g for packs under 1 kg at line speed, depending on belt speed, pack length and environment. Washdown lines and air currents affect accuracy — we specify the load cell, belt and enclosure for your conditions.

Do I need a legal-for-trade (MID) checkweigher?

If the checkweigher is the sole means of controlling net quantity for e-marked packs, many EU authorities require MID-approved instruments. We supply and arrange initial verification where needed.

Can the checkweigher share a frame with a metal detector?

Yes. Combination units (Thermo and Fortress) put both inspections on one frame with a single reject and one operator screen — less floor space, one integration.
