Choosing a checkweigher for product inspection usually starts with a single question: how will it integrate with the conveyor or packaging line you already run? The market includes powered weigh tables that fit into a compact footprint and inline conveyor systems that handle product flow continuously. The four units here span a wide listed-price range-from $3,000 to $5,500-so the decision is as much about system fit as it is about budget. Before you dive into the specs, think about the product weight you need to verify, the physical space in your facility, and whether you want a unit that moves items along or simply weighs them in place. Below is a side-by-side look at what each unit offers, starting with a quick assessment.
Quick Take
The Mettler Toledo SWC is the only new unit in the group, pairing a roller conveyor scale with an IND570 display. Among the used options, the Alpha Checkweighers PW-12 Conveyor Checkweigher System is the only stainless inline dynamic system. The two powered weigh tables from Alpha Checkweigher and All-Fill share similar dimensions and weight, but differ in listed price and manufacturer.

Product Notes
#### ALPHA CHECKWEIGHER PW-12 Powered Weigh Table Conveyor scale
This used powered weigh table is listed at $5,500 and carries a 2014 manufacture date, with a compact 42 x 42 x 75-inch footprint and a 252-lb weight. Its serial number 980610 and working condition are noted in the description, along with a 110V single-phase supply and 24VDC control voltage. If you need a ready-to-integrate weigh table from Alpha Checkweigher, this is the one to consider. The obvious limitation is the price: it's the highest listed price in the group, so you'll want to be sure the 2014 build and Alpha branding justify the difference. The 2014 build date is the most recent among the used weigh tables, which could be a factor if you want a newer unit for your line.
#### ALL-FILL PW-12 CHECKWEIGHER Powered Weigh Table USED
At $3,000, this All-Fill unit is one of two PW-12 weigh tables at the same listed price. It shares the 42 x 42 x 75-inch dimensions and 252-lb weight with the Alpha PW-12, but it comes from All-Fill and has a manufacture date of 5/2009. The description mentions a motor control interface and the same 110V/24VDC electrical setup. If you're looking to keep the initial outlay low and can work with an older used unit, this is a straightforward pick. The trade-off is that it's the oldest machine in the group, so you may want to plan for more careful inspection before putting it into service.
#### METTLER TOLEDO SWC Checkweigher Roller Conveyor Scale IND570 indicator 200lb cap
This is the only new unit in the comparison, listed at $3,499.99. It features a 200 lb normal capacity with 0.1 lb increments, a Class III accuracy rating, and an integrated IND570 display. The description also says it comes with a 15A 125V plug and a bagged hardware kit, and it's described as new unused on its original pallet. If you want new equipment with a known capacity and a display already built in, this is the unit to compare against your requirements. The limitation is that it's a roller conveyor scale, so you'll need to consider how it fits into your existing line.
#### Alpha Checkweighers PW-12 Conveyor Checkweigher System Stainless Inline USED
Listed at $3,000, this used inline system from Alpha Checkweighers provides continuous dynamic weighing through an integrated infeed, weigh section, and discharge conveyor. It's a 2015 model with a stainless construction, and it weighs 450 lbs with dimensions of 60 x 46 x 78 inches. This makes it the largest unit in the group, so floor space is a real consideration. The serial number 980643 and 2015 date of manufacture are listed in the description, so you have a clear reference for the unit's age. For lines that need inline product flow rather than a stand-alone weigh table, this is the only stainless option here. The trade-off is its footprint and weight: at 450 lbs, you'll need to plan for installation and may need additional support for the conveyor setup.
Final Recommendation
For a compact powered weigh table, the All-Fill PW-12 lists at a lower price than the Alpha PW-12; the Alpha is a newer used unit. For inline inspection, the Alpha Checkweighers PW-12 Conveyor Checkweigher System is the stainless option. If you want new equipment, the Mettler Toledo SWC is the only new unit and includes a 200 lb capacity and IND570 display.
