Choosing a checkweigher rests on five parameters: pack weight range, pack dimensions, line speed (packs per minute), required accuracy and reject-system type. Your real line data decides the model better than any catalogue figure.
Checkweighers look alike but differ widely in load-cell capacity, belt length and reject mechanism. A few simple questions before purchase can prevent a wrong choice.
A pusher arm suits medium and heavy packs, air blast suits light, fast packs, and a drop flap suits light products and small packs. If the line needs separate rejection of underweight and overweight packs, the checkweigher needs separate outputs or multi-stage rejection.
If line space is limited and you also need metal inspection, a combined metal detector and checkweigher on one belt is a good option. If your line changes product and pack often, two separate machines are more flexible. See checkweigher and metal detector placement for layouts.
Total cost includes purchase, installation, training, annual calibration, reference weights and spares, set against reduced giveaway and avoided penalties and complaints. A cheaper machine that does not fit your weight and speed ends up costing more.

Pack weight range, pack dimensions, line speed, required accuracy and reject-system type.
It depends on pack weight, shape and line speed; a pusher arm is common for heavier packs and air blast for light, fast packs.
When line space is limited and you need both inspections.
Weight range, pack dimensions, line speed, packaging material and whether you need automatic reject and PLC connection.
