KERN 357-07 – 100 g OIML M2 calibration weight, knob form, stainless steel

A KERN 357-07 calibration weight designed for routine scale verification and workshop or laboratory checks where a compact, robust reference mass is required.

  • OIML class M2 certified
  • Nominal mass 100 g
  • Finely turned stainless steel finish
  • Knob form for secure handling

Certified accuracy for routine verification

The weight is specified as OIML Class M2, a recognised standard for calibration masses used in routine verification and non-precision laboratory checks. The 100 g nominal mass provides a stable reference for balances and scales where Class M2 tolerances are applicable. Using a certified reference reduces uncertainty in routine checks and supports traceable results, helping maintain measurement consistency across production and inspection points.

Robust stainless-steel construction for daily use

Manufactured from finely turned stainless steel, the reference mass resists corrosion and surface wear in workshop environments, extending service life and preserving measurement stability. The knob form simplifies handling and placement, reducing the risk of finger oil or contamination affecting the mass. Durable construction also minimises the need for frequent replacement, supporting efficient maintenance cycles and reliable daily verification routines.

Practical fit into calibration workflows

Compact design and clear specification make this calibration mass straightforward to integrate into existing calibration procedures. The compact knob facilitates quick, repeatable placement on balances, speeding up routine checks and reducing downtime. Clear labelling and certification support documentation requirements for internal quality control and audit trails, making the component a practical tool for production, workshop and inspection areas.
