MSI 4260 Port-A-Weigh Digital Crane Scale
When MSI introduced the original MSI-4260 Port-A-Weigh in 1979, it quickly replaced mechanical crane scales in the Alaskan fishing industry. Exceptional ruggedness and accuracy made it the only legal-for-trade scale for this harsh marine environment. With periodic design updates, the Port-A-Weigh remains the workhorse of the heavy-duty crane scale market.
Delivering you an accuracy of 0.1% of the applied load, the Port-A-Weigh is NTEP approved for use in commercial trade.
