Net Weigh Scales – the Heart of Bagging Profitability

With thousands of net weigh scales in use worldwide, the scale is often the most overlooked part of any automatic bagging installation.   Most net weigh scales in use today were developed over 30-40 years ago.   Even recent “new designs” are still based on outdated design concepts and do not offer significant improvements to this important category of bagging technology.

Model 600NW Gravity Feed Scale

Hamer built a better product from the ground up

When Hamer designed the Model 600 Net Weigh Bagging Scale we looked at this technology from a whole new perspective. Our experience in form, fill and seal automation exposed us to virtually every design and manufacturer of net weigh scales. This is what our customers told us they needed in their bagging operations:


  • Accuracy/Repeatability to reduce product giveaway
  • Durability of machine parts with less maintenance
  • Speed as historic simplex/duplex designs were slow and expensive
  • Ease-of-use, many old designs are confusing to operate


We met the challenges our customers presented. The Model 600NW beats all scale designs, hands down. With almost 200 units in operation since its launch in 2007, it has become the standard by which all other scales are measured. Here’s why:

  • Fastest design available. Innovative mechanical/software design increases material processing speeds by 50% over most other scales
  • Extremely accurate at high speeds. With repeatability of .1 lb. on 50 lb. fills, each and every 50 lb. bag can be measured to 1-2 oz. accuracy to reduce overfilling and product give-away
  • More steel construction. Designed for high-speed use with a wide variety of products, it’s built with double the steel of competing designs.   With over 200 units in the field, it’s the proven industrial design and the standard by which others are measured.
