Quick Take
When your line needs to confirm package weights as products move past, the choice between checkweighers usually comes down to how much automation you want and whether you're comfortable with used equipment. The four systems here range from a USD 3,000 used Alpha PW-12 inline conveyor checkweigher to a USD 9,730 new 110V auto conveyor checkweigher. In between, a new SelLeton SL-CW-2x3-200 offers a 200 lb capacity, while a second used Alpha PW-12 is set up as a powered weigh table for packaging and filling integration.

Decision Matrix
- Alpha PW-12 Conveyor Checkweigher System: Used inline dynamic weighing with integrated infeed, weigh section, and discharge conveyor; the listing also notes a 450 lb equipment weight and 60 x 46 x 78 dimensions.
- Maisutseb 110V Inline Checkweigher: New automated conveyor checkweigher with a powered weighing conveyor, precision load cell, motorized roller rejection section with a stainless steel pusher, and a gravity roller collection section.
- SelLeton SL-CW-2x3-200: New industrial inline checkweigher.
- Alpha PW-12 Powered Weigh Table: Used powered weigh table designed for packaging and filling integration, with a 24 VDC control voltage and a 110V, 1-phase, 60 Hz power supply.
Product Notes
Alpha Checkweighers PW-12 Conveyor Checkweigher System Stainless Inline USED
The strongest reason to consider this used Alpha PW-12 is the integrated conveyor setup: it pairs infeed, weigh, and discharge sections for inline dynamic weighing, which is useful if you want a straightforward weight check on a moving line. The listing provides concrete handling details like 110 VAC supply, 24 VDC control interface, 450 lb weight, and 60 x 46 x 78 dimensions. The limitation is its used condition and 2015 production year; this is not a new machine, and the description emphasizes weighing rather than automatic reject sorting. If your budget points to the lower end of the range and you can work with a used unit, this system gives you a clear conveyor-based weighing path.
110V Inline Conveyor Checkweigher 3-Section Auto Conveyor Weight Checker 110lbs
This new Maisutseb checkweigher is the one to choose when you want the weighing and sorting process to happen automatically. Its three-section layout combines a powered weighing conveyor with a precision load cell, a motorized roller rejection section with a stainless steel pusher, and a gravity roller collection section, so products can be channeled into accept or reject paths without manual handling. The title specifies a 110 lb capacity, so it's aimed at lighter packaged goods. The trade-off is that this rating makes it best suited to lighter items; if your line handles heavier loads, you would need to look at the higher-capacity unit in this group.
SL-CW-2x3-200 Industrial Conveyor Checkweigher - 200 lb Capacity \| 4-20mA Output
This SelLeton unit is the only checkweigher here that lists a 200 lb capacity, making it a fit for heavier boxes, bags, or cartons. The 4-20mA output is a clear integration point for feeding weight data into a control system. It's a new unit, so you avoid the used-equipment variable that comes with the two Alpha PW-12 listings. The limitation is that the description positions it as an inline weighing system for weight verification, rather than a sortation machine; if automatic reject sorting is essential, this unit is best understood as a weight-verification conveyor. If your priority is capacity and a signal output rather than automatic sorting, this option aligns with that goal.
ALPHA CHECKWEIGHER PW-12 Powered Weigh Table Conveyor scale
This used Alpha PW-12 is configured as a powered weigh table, not a full inline checkweigher. That makes it a good match if you want to integrate weighing into an existing packaging or filling line rather than buy a standalone conveyor system. The listing includes a 252 lb weight, 42 x 42 x 75 dimensions, 110V single-phase power, and 24VDC control voltage, with a manufacture date of 6/2014. The limitation is that it's a weigh table, so for sorting duties you would need a separate checkweigher with a reject section; it's for applications where the surrounding line handles transport and you just need a controlled weighing point.
Final Recommendation by Use Case
- If you want automated accept/reject sorting in one machine, the 110V Inline Conveyor Checkweigher with its three-section conveyor system is the clear match.
- If you need to weigh heavier products and want a new unit, the SL-CW-2x3-200 Industrial Conveyor Checkweigher with its 4-20mA output is the one to consider.
- If you prefer a lower-cost used inline conveyor system for basic weight verification, the Alpha Checkweighers PW-12 Conveyor Checkweigher System fits that role.
- If your line already has conveying and you just need a powered weighing point for filling or packaging integration, the ALPHA CHECKWEIGHER PW-12 Powered Weigh Table Conveyor scale is a more specialized option.
