When you're inspecting products on a packaging line, the core question isn't just whether an item is heavy or light-it's whether your checkweighing setup can flag tiny deviations quickly and repeatably. If you need a bench-friendly unit for bags, boxes, or discrete parts up to 25 pounds, the Rice Lake CW-90-5 over/under checkweigher deserves a close look.
Quick Verdict
This NTEP-listed checkweigher combines a 0.005 lb readability with a 12 x 12 inch pan and 115 VAC operation. At USD 1,519.88, it's a serious investment for a production line that needs accurate over/under sorting without a full-scale conveyor system.
Who It Suits
This unit fits operations where workers place items on a pan and need a clear over/under reading to route them. The 25 lb capacity covers common packages, while the 0.005 lb increments support fine tolerance work. The NTEP listing points toward legal-for-trade use in suitable applications, making it a match for quality-control stations that must document accuracy.
What Stands Out From the Listed Details
The headline feature is the fine readability. At 0.005 lb, you're getting roughly 0.08 ounces of resolution, which is useful for catching underfills or overfills on items where small variances trigger rejects. The 12x12 pan gives a stable surface for boxes or bags, and the 115VAC plug-in operation is straightforward for a fixed production station. The model number, CW-90-25-12, reinforces the 25 lb capacity and 12-inch pan sizing.
Meaningful Trade-Offs
The capacity of 25 lb sets a clear ceiling; heavier items will require a larger checkweigher. The fine readability is a strength, but it also means the unit is designed for deliberate, manual placement rather than continuous high-speed flow-so if your line relies on automated sorting, this pan-style checkweigher may not keep pace. Also, at USD 1,519.88, you'll want to be sure the 0.005 lb resolution is necessary for your product mix; a coarser unit might suffice for some operations.
Bottom Line
For production-line quality control where legal-for-trade status and fine resolution matter, the Rice Lake CW-90-5 is a capable, focused tool. It earns consideration if your line handles up to 25 lb items and you need reliable over/under readings without expanding to a conveyor-based system.

Need to inspect package weights with tight tolerance? The 0.005 lb readability lets you spot small deviations that standard scales might miss. The 25 lb capacity, however, is the limiting factor-if your products trend heavier, you'll have to look beyond this model.
