Key features of the Hamer 100GW:

  • High speed and accuracy: The Hamer 100GW can fill bags with a weight range of 10 lbs. to 110 lbs. (5 kg to 50 kg) at a rate of up to 16 bags per minute, with an accuracy of +/- 1 oz. (product dependent)
  • Dual load cell design: This eliminates inaccuracies inherent in single load cell designs, ensuring consistent and reliable weighing
  • Adjustable bulk/dribble flow settings: This allows you to optimize the filling process for different types of products
  • Rice Lake 720i digital weigh indicator: This indicator features a high-visibility display and easy-to-use controls

  • Lbs./kg weight display: You can choose to display the weight in pounds or kilograms
  • Bag clamp whisker switch: This switch automatically detects the presence of a bag and initiates the filling process
  • Bag hold switch: This switch allows you to hold the bag in place after it has been filled
  • Bag counter: This keeps track of the number of bags that have been filled
  • Auto zero: This feature automatically zeros the scale before each filling cycle
  • Auto bag in place: This feature ensures that the bag is properly positioned before filling begins
  • Auto hold for underweight bags: This feature prevents underweight bags from being released
  • 4″ diameter dust port: This port helps to keep dust and debris contained
  • Paper, poly, polywoven, or woven bags: The Hamer 100GW can be used with a variety of bag types
  • Durable carbon steel construction: This ensures that the scale is built to last

Benefits of the Hamer 100GW:

  • Increased productivity: The Hamer 100GW can help you to increase your production output by filling bags more quickly and accurately
  • Reduced waste: The accurate weighing of the Hamer 100GW helps to prevent overfilling and underfilling of bags, which can save you money on product
  • Improved safety: The automatic features of the Hamer 100GW help to reduce the risk of injuries to workers
  • Easier operation: The Hamer 100GW is easy to use, even for workers with limited training
  • Versatility: The Hamer 100GW can be used with a variety of products and bag types

Quick Comparison of Hamer 100GW and Hamer Model HGB
Choosing between the Hamer 100GW and Hamer Model HGB depends on your specific needs and priorities. Here’s a quick comparison to help you decide:


  • 100GW: Electronic. The scale automatically weighs the product and stops filling when the desired weight is reached
  • HGB: Manual. The operator pulls a lever to open the gate and fill the bag. Weight is controlled by adjusting the filling time


  • 100GW: Up to 16 bags per minute
  • HGB: Varies depending on the operator


  • 100GW: +/- 2 ounces
  • HGB: +/- 4 ounces


  • 100GW: Limited to small/medium bags
  • HGB: Handles a wide range of bag sizes and weights

Dust Control:

  • 100GW: Optional dust collection system
  • HGB: Minimal

Ease of Use:

  • 100GW: Simple push-button operation
  • HGB: Requires training and manual operation


  • 100GW: Minimal maintenance
  • HGB: Regular calibration and service required

Cost comparison:

  • 100GW: More expensive
  • HGB: More affordable

Choosing the right Hamer scale for your needs:

  • 100GW is ideal for: High-volume operations; precise filling requirements; dust control concerns; ease of use; minimal maintenance
  • HGB is ideal for: Low-volume operations; tight budgets; manual bag handling; simple weighing needs
  • Material being weighed: Both scales can handle dry goods, but the 100GW may be better suited for fine or dusty materials
  • Desired level of automation: If you need a quick and efficient filling process, the 100GW is the better choice
  • Budget: The 100GW will save you time and labor in the long run, but the HGB is a more affordable option
