A&D Weighing AD-4329A Digital Weighing Indicator - Legal For Trade Canada

AD-4329A multi-functional weight indicator is ideal for use in warehouses, production lines, shipping and receiving departments and for filling, batching and checkweighing applications. Features vacuum fluorescent display, Comparator output to optional relays, and accumulative data memory. Includes Set-point comparison for batching applications (Near Zero/Prelim/Target/Free Fall)

Selectable weighing ranges (up to triple ranges) and standard RS-232C communication make AD-4329A versatile in many applications. Powers up to 8 units of load cells at 350Ω. 

  • Triple weight range to select the right weighing range for your application
  • 4-point digital linearization
  • 1/20,000 displayed count resolution
  • Can be controlled via external input
