10 kg Precision Test Weight Knob Form, OIML Class M1, Stainless Steel Turned - KERN

Product information "10 kg Precision Test Weight Knob Form, OIML Class M1, Stainless Steel Turned - KERN"

Take advantage of the combination of OIML class M1 accuracy, a 10 kg nominal mass and a fine-turned stainless steel finish for reliable calibration cycles; order the KERN 347-14 calibration weight directly via Metav Werkzeuge or consult our advisors for DAkkS calibration options.

KERN 347-14 — 10 kg calibration weight, OIML class M1, knob form

A KERN 347-14 calibration weight designed for precise scale verification and routine laboratory or workshop checks.

  • OIML class M1 accuracy
  • Nominal mass 10 kg
  • Fine-turned stainless steel finish
  • Knob form for secure handling

Consistent accuracy for dependable results

The weight meets OIML class M1 requirements with a declared tolerance of 500 mg, providing a dependable reference for verification and quality control. This level of conformity reduces measurement uncertainty during routine calibrations and supports consistent process control across production or laboratory environments. By using a verified reference mass with a clear tolerance band, audits and internal checks become more straightforward, and measurement drift can be identified and corrected quickly, maintaining operational efficiency.

Robust design that endures daily use

Manufactured from stainless steel and precision turned, the mass offers resistance to corrosion and maintains surface integrity after repeated handling. The knob form simplifies placement and removal from weighing instruments, lowering the risk of accidental contact and preserving the mass value. Durable construction means fewer replacements and less downtime, so maintenance cycles remain predictable and workshop throughput is sustained.

Traceability and calibration aligned with current standards

With the EG declaration on calibration weights no longer possible after 30 November 2025, a DAkkS calibration is the recommended route for traceable documentation. A documented calibration route ensures compliance with internal quality systems and external audits. Choosing a traceable calibration service for this reference mass secures measurement history for long-term record-keeping and supports conformity assessments where documented evidence of accuracy is required.
