Choosing a metal detector for a food conveyor line usually comes down to a single tension: do you want a new unit with modern adjustment features, or a used industrial detector at a lower listed price? These four listings answer that question with very different tradeoffs.
The three new machines-from TECHTONGDA, BANFLUXION, and INTBUYING-share the same SA-990 model name and similar 400mm x 150mm detection area. The fourth is a used Lock Inspection Systems MET30+ with its own conveyor aperture. Here is how they compare for product inspection and checkweighing tasks.
Quick take
If you need a new conveyor metal detector, the BANFLUXION unit adds 100 product storage parameters for multi-SKU runs. If adjustable speed and sensitivity matter more than recipe memory, the TECHTONGDA unit lists those controls. If you want a new unit with a US country of origin in the listing, the INTBUYING machine is the only one with that detail. The Lock MET30+ is the used-equipment choice and sits at the bottom of the listed price range.

Product notes
TECHTONGDA Metal Foreign Object Detection Machine Food Conveyor Metal Detector Inspection
This new unit is the one to look at if you want adjustable conveyor operation on a food inspection line. The listed specs include a maximum single-piece load of 25kg and an adjustable transfer speed of 5-28m/min, along with sensitivity settings from 0 to 99. That range makes it easier to match the detector to different product sizes and line speeds. The main limitation is that the listed price sits near the top of the group, with only the INTBUYING unit marginally higher. If you don't need adjustable speed or sensitivity, you could pay less on the new-unit side.
BANFLUXION Industrial Food Conveyor Metal Detector Inspection Machine for Food Safety 110V
This new SA-990 unit is the least expensive of the three new machines. It also includes a 100-product storage memory, which is a practical feature if you run multiple SKUs and want to recall settings. The listed specs include a 120W motor and 158W total power on a 110V supply. The limitation is that, aside from the storage memory and slightly lower price, it shares the same model name and detection area as the other two new units. For a shopper focused on a new detector with recipe storage, this is the one to weigh first.
INTBUYING 110VFood Conveyor Metal Detector Food Metal Detection Machine Inspection Machine
The INTBUYING unit is the only one of the three new machines with a US country of origin stated in the listing, and it also includes a UPC and GTIN. If your procurement process benefits from those identifiers, this is the unit that provides them. The listed price is the highest in the set, though the difference from the other new units is only a few dollars. It is also labeled as a ground-search type in the attribute list, which is a different classification from the conveyor-mounted wording used in the title. For new-equipment shoppers who want US origin visible, this option stands out, but you're paying essentially the same as the TECHTONGDA unit.
Lock Inspection Systems MET30+ Metal Detector for Conveyor 19-1/2" X 11-1/2"
The Lock unit is the outlier in this group: it is the only used detector and sits at the bottom of the listed price range. The title gives a conveyor aperture of 19-1/2" X 11-1/2" and the model name MET30+ from Lock Inspection Systems. Because it's used, condition is a key consideration. If you're comfortable buying used industrial equipment and want to stay well below the new-unit price range, this is the one to compare against the new SA-990 machines. The tradeoff is that the listing centers on the model name and aperture, so the buy decision rests largely on the used condition and the Lock brand name.
Final recommendation
Match the option to your line speed, product load, and record-keeping needs. For a new detector with the ability to store multiple product settings, the BANFLUXION unit is the least expensive of the new machines and includes 100 storage parameters. If adjustability is more important than recipe memory, the TECHTONGDA unit gives you adjustable transfer speed and sensitivity. For a shopper who wants new equipment with US origin listed, the INTBUYING unit is the only one that states it. The Lock MET30+ is the used budget pick if your line fits the 19-1/2" x 11-1/2" conveyor aperture.
