Precision balance KERN EW with robust tuning fork measuring system

• 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
• Totalising of pieces when counting

FEATURES

• Adjusting program (CAL): For quick setting of the balance's accuracy. External adjusting weight required.
• Data interface RS-232: To connect the balance to a printer, PC or network
• GLP/ISO log: with weight, date and time. Only with KERN printers, see Accessories
• Piece counting: Reference quantities selectable. Display can be switched from piece to weight.
• Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams.
• Weighing units: Can be switched to e.g. nonmetric units at the touch of a key. See balance model.
• Weighing with tolerance range: Upper and lower limiting can be programmed individually, e. g. sorting and portioning.
• Suspended weighing: load support with hook on the underside of the balance.
• Universal mains adapter: with universal input and optional input socket adapters for EU, GB, USA
• Tuning fork principle: A resonating body (like a tuning fork) is electromagnetically excited, causing it to oscillate. The measured value is calculated via the change in frequency correspon
• 3 years warranty

OPTIONS

• Rechargeable battery pack: rechargeable set
• Universal mains adapter: with universal input and optional input socket adapters for EU, GB, USA
• Calibration certificate possible
