Combine Hasler's Dynamic Weighing Platform (WJDWP) with the WJ185, WJ220, or WJ250, and you can process mixed weight mail at speeds up to 130 LPM. The ability to “weigh in motion” means there's nothing to sort or weigh by hand. You'll reduce labor costs and increase productivity with the simple touch of a button. The WJDWP handles dynamic, batch or pass thru processing, and I automatically calculates the rate for oversized mail without operator intervention.
