Kern PES / PEJ Precision Scales

Kern
115000

Robust, verified, and high-capacity weighing solutions

The Kern PES and PEJ precision balances are designed for professional laboratory and industrial use, offering high precision even in heavy-duty applications. The PES models feature manual external calibration, while the PEJ models come equipped with automatic internal adjustment and are verification-ready according to NAWI 2014/31/EU.

With capacities up to 31,000 g and resolutions as fine as 0.001 g, these balances are ideal for tasks requiring consistent accuracy and traceability. Their robust metal housing and stainless-steel platforms provide durability in high-throughput environments.

Key Features

  • Calibration: PES – external calibration via CAL program; PEJ – internal automatic adjustment
  • Verification: PEJ models are legal-for-trade (models ending in "M")
  • Display: Bright fluorescent display with high contrast, 14 mm digit height
  • Draught shield: Standard on models with small pan size A (170×150×100 mm internal space)
  • Construction: Metal housing, stainless steel pan, and optional underfloor weighing hook
  • Connectivity: RS-232 interface; optional relay outputs and qualification packages
