Analytical balance KERN ABT 100-5NM approved
  • -10%
KERN & SOHN GmbH Analytical balance KERN ABT 100-5NM

The premium model with single-cell weighing system

Internal adjusting (CAL): Quick setting of the balance's accuracy with internal adjusting weight (motordriven). Data interface RS-232: To connect the balance to a printer, PC or network GLP/ISO log: the balance displays the weight, date and time, regardless of printer connected Piece counting: Reference quantities selectable. Display can be switched from piece to weight. Recipe level A: Separate memory for the weight of the tare container and the recipe ingredients (net total). Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams. Suspended weighing: load support with hook on the underside of the balance. Weighing units: Can be switched to e.g. nonmetric units at the touch of a key. See balance model. Universal mains adapter: with universal input and optional input socket adapters for EU, GB, USASingle cell technology: Advanced version of the classic electromagnetic force compensation principle. The load cells are milled from a single aluminium block achieving high mechanical strength, fast response characteristics and greater measurement stability, e.g. temperature behaviour and high reproducibility. 3 years warranty
