Choosing a conveyor metal detector for a product inspection checkweighing line means balancing belt width, build material, detection capability, and whether you are willing to buy used. The four units here span a wide price range: the lowest listed price sits on a used Mettler Toledo package, while the highest sits on a new digital stainless steel machine, with more than $5,000 between them.
Quick Take
Four conveyor metal detectors are in this comparison, and the spread is meaningful. At the low end is a used Mettler Toledo DMS 20 + EGK48-60NV conveyor belt unit; at the high end is a new CHONGYTTUO digital model with a wider belt and a stainless steel body. In between are two new 110V machines from HayWHNKN and BANFLUXION with nearly identical widths and prices.
Before you commit, decide whether the machine will run on a dedicated line or share space with other equipment. That determines whether belt width and detection height matter more than the price spread. A used unit can get you into the category at a much lower listed price, but it brings visible wear; a new unit gives you a finished piece of equipment with published dimensions.

Use that matrix as a shortcut, but read the product notes below for the trade-offs that separate the two similarly sized new machines.
Product Notes
Industrial Food Conveyor Belt Metal Detector 110V 400mm Width Fe Φ≥1.0mm
At $5,547.60, this HayWHNKN unit is the lower-priced new 400 mm option. It is designed to detect iron and non-ferrous metals, including copper, aluminum, and stainless steel, and the title specifies a ferrous threshold of Fe Φ≥1.0mm. That makes it a direct fit if your main concern is iron contamination in food or packaging lines. The price difference from the BANFLUXION machine is less than $2, so the decision between these two will likely come down to which brand you want on the equipment label. If you are shopping on a tight budget but still want new, this is the lower-cost route of the two.
Industrial Food Conveyor Metal Detector Inspection Machine for Food Safety 110V
At $5,549.44, this BANFLUXION machine adds a stated detection height of 150 mm to the 400 mm detection width. It also lists a 120 W motor and 158 W power consumption, plus storage for 100 product settings. That storage capacity is practical if you regularly switch between different items on the same line, because you can call up saved inspection profiles instead of re-entering parameters. The extra cost over the HayWHNKN unit is minimal. The limitation is the fixed 150 mm detection height, so if your products are taller than that, this unit may not work for your line.
Industrial Digital Metal Detector Conveyor Belt Food Metal Detection Machine
At $6,256.00, this CHONGYTTUO unit is the highest listed price, but it is the only one with a stated 450 mm belt width and a 304 stainless steel body. The belt is food-grade white PU, and the speed adjusts from 20 to 40 m/min. It uses a 7-inch touchscreen console and a three-color tower light with an audible buzzer, so alarms are both visible and audible. If you need a wider belt for larger products, this is the clear choice. The main limitation is the price jump: it costs roughly $700 more than either of the two new machines.
Mettler Toledo DMS 20 + EGK48-60NV EG Metal Detector Conveyor Belt
At $1,167.95, this used Mettler Toledo unit is the lowest listed price by a wide margin. The unit is described as having good external condition and working function, with discoloration and ink marks, so you should expect some cosmetic wear. It is sold as a single piece and pairs the DMS 20 with the EGK48-60NV conveyor belt. For someone who wants a metal detector conveyor setup on a product inspection line without spending new-machine money, this is the most direct route. The limitation is that it is a used unit, so you are accepting visible wear and the condition described rather than the untouched state of a new machine.
Final Recommendation
Choose the Mettler Toledo DMS 20 + EGK48-60NV if you need the lowest listed price and are comfortable with a used unit. Prefer the BANFLUXION Industrial Food Conveyor Metal Detector Inspection Machine if you want a new unit with a stated detection height. Pick the HayWHNKN Industrial Food Conveyor Belt Metal Detector if you want a new unit with a slightly lower listed price. Select the Industrial Digital Metal Detector Conveyor Belt if you need a 450 mm food-grade belt, a 304 stainless steel body, and adjustable belt speed.
