1 kg Calibration Weight, Knob Shape, Fine-Turned Stainless Steel, OIML M1, 50 mg Tolerance - KERN

Product information "1 kg Calibration Weight, Knob Shape, Fine-Turned Stainless Steel, OIML M1, 50 mg Tolerance - KERN"

Take advantage of the combination of certified accuracy, robust stainless-steel construction and ergonomic knob design for dependable calibration workflows; order the weight directly via Metav Werkzeuge or consult our specialists for DAkkS calibration guidance.

KERN 347-11 — Test weight (OIML M1, 1 kg, fine-turned stainless steel, knob)

the KERN 347-11 is a precision OIML M1 test weight designed for calibration of balances and laboratory scales in workshops and quality-control environments

  • OIML class M1 certified
  • Nominal mass 1 kg
  • Fine-turned stainless steel finish
  • Knob form for safe handling

Assured accuracy for routine and accredited checks

This test weight delivers traceable accuracy thanks to its classification as OIML M1 with a specified tolerance of 50 mg, making it suitable for medium-accuracy calibrations and routine verification of laboratory and industrial balances. The defined tolerance provides a clear, measurable basis for conformity checks and reduces uncertainty in daily calibration routines. Where legal-for-trade type approval is affected by regulatory changes, the measured specification still enables precise in-house checks and documented performance comparisons.

Robust material and ergonomic handling for repeatable use

Manufactured from fine-turned stainless steel, the weight resists corrosion and retains its calibrated surface finish through repeated handling and cleaning cycles; this supports long service intervals and consistent mass values. The knob form allows controlled placement and removal on sensitive pans, reducing the risk of contact-related damage and improving operator efficiency. The durable construction contributes to lower lifecycle disturbance and sustained measurement reliability in busy workshops and labs.

Traceability, calibration options and regulatory note

Given the regulatory change that ends EG type approval from 30.11.2025, the product documentation recommends DAkkS calibration, which is equivalent for most professional applications and preserves traceability to national standards. Calibration and documentation options ensure clear audit trails and support quality-management systems. For organisations requiring specific certificates or repeat calibration intervals, the combination of a certified test weight and documented DAkkS calibration provides a robust compliance path.
