KERN 337-07 calibration weight – 100 g, OIML F2, stainless steel

A KERN 337-07 single calibration weight in button form, designed for verification and routine calibration of precision balances in laboratories and workshops.

  • OIML class F2 precision
  • Nominal value 100 g
  • Fine-turned stainless steel
  • Button form 22×39 mm

Precision where measurement counts

The OIML F2 classification and a stated tolerance of 1.6 mg make this calibration weight suitable for high-accuracy verification tasks and internal quality control. As a 100 g reference mass, it provides a compact, traceable standard that supports reproducible results on analytical and precision balances. Choosing a weight with defined OIML conformity reduces uncertainty in routine checks and helps meet audit and certification requirements, allowing calibration cycles to be planned with confidence.

Durable construction for repeatable results

Manufactured from fine-turned stainless steel, the reference mass offers excellent surface integrity and corrosion resistance, which preserves the metrological properties over time. The button form simplifies handling and placement on small balance pans, while the compact 22×39 mm geometry minimises thermal and air-flow influences during weighing. This combination of material and shape reduces wear and maintains mass stability, decreasing the frequency of replacements and interventions.

Practical integration into calibration routines

Designed as a reference mass for balance verification, this weight supports efficient calibration workflows: small footprint for bench use, clear classification for documentation, and a robust finish for everyday handling. A protective case is recommended given the tight tolerance of the class; Metav offers suitable etuis and accessory options to protect the reference mass during storage and transport. Using a well-documented single weight like this reduces downtime during routine checks and simplifies traceability records.

Trusted supply and quality assurance

Produced by a recognised metrology manufacturer in Germany and supplied with full identification, the calibration mass is designed for professional environments where repeatability and traceability are essential. Relying on certified reference masses contributes directly to process reliability and customer confidence in measured results. Metav’s procurement and quality-filtering at Emmerich ensures consistent product availability and compliant delivery for industrial and laboratory use.
