The classic balance with robust tuning fork measuring system

  • only EG-NM: Internal adjustment by rotary knob on the side. Guarantees high degree of accuracy and makes the balance independent of its location
  • only EW-NM: Adjusting program CAL for quick setting of the balance accuracy using an external test weight
  • Capacity display: A bar lights up to show how much of the weighing range is still available
  • Precise counting: The automatic reference weight optimisation of reference weight gradually improves the averag piece weight value
  • GLP/ISO record keeping of weight values
  • Percentage determination
  • Totalising of pieces when counting
  • Draught shield standard for models with weighing plate size Ø 118 mm. Removable metal cover with pipette opening, weighing space WxDxH 158×130×78 mm
