Precision Scale for Pharmaceutical Application

Part#: EW-series
Supplier: KERN
Calibration Certificate: available on request

This KERN EW DIGITAL Precision Scale (series) is extremely popular with light industrial installation or laboratory facilities. The new KERN EW-series has a minimum weighing capacity of 220g and 0,001 g readability (depending on model).


  • Adjusting program CALIBRATION 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
  • Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams.
  • Weighing with tolerance range: Upper and lower limiting can be programmed individually, e. g. sorting and portioning.
  • Weighing units: Can be switched to e.g. nonmetric units at the touch of a key.
  • 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 correspondence
  • Draught shield standard for models with weighing plate size Ø 118 mm. Removable metal cover with pipette opening, weighing space WxDxH 158x130x78 mm


  • kern-accesories-for-ew-scale.jpgProtective working cover over keyboard and housing
  • Rechargeable battery pack internal, operating time up to 32 h, charging time approx. 12 h, charge status indicator on display. AUTO-OFF function to preserve the battery, can be switched off
  • Large glass draught shield with 3 sliding doors for easy access to the items being weighed, Weighing space WxDxH 150x140x130 mm, can be retrofitted for models with weighing plate size 180x160 mm
  • Loop for underfloor weighing
  • Matrix needle printer for KERN-Balances with Data interface RS-232
  • Thermal printer for KERN-Balances with Data interface RS-232
  • Statistics printer for KERN-Balances with Data interface RS-232
  • Ioniser to neutralise electrostatic charge
  • Tare pan made from stainless steel, ØxH 57x16 mm
  • RS-232/Ethernet adapter: Adapter to connect balances, force measuring devices etc. with an RS 232 interface to an IP-based Ethernet network
  • Software Balance Connection
  • RS-232/WiFi adapte: High-quality adapter for the wireless connection of balances, force measuring devices etc. to an RS-232 interface to WLAN-enabled devices, such as tablets, laptops, Smartphones etc.
