1 kg Precision Test Weight Knob Shape Stainless Steel Fine-Turned OIML F2, 16 mg Tolerance - KERN

Product information "1 kg Precision Test Weight Knob Shape Stainless Steel Fine-Turned OIML F2, 16 mg Tolerance - KERN"

Take advantage of precise mass accuracy, robust fine‑turned stainless steel construction, and a practical knob form that eases handling during routine calibrations; order the KERN 337-11 directly via Metav Werkzeuge or ask our consultants if needed.

KERN 337-11 — 1 kg OIML F2 calibration weight, fine‑turned stainless steel, knob form

A KERN 337-11 calibration weight designed for laboratory, workshop and service use for the verification and routine calibration of precision scales and balances.

  • OIML class F2 for accurate calibration
  • 1 kg nominal mass with knob form
  • Fine‑turned stainless steel construction

Reliable traceability and repeatable results for measurement routines

The finely finished 1 kg mass delivers consistent reference values that support routine verification and in‑service checks. Certified to OIML F2, the device offers a narrow tolerance of 16 mg, which reduces uncertainty in everyday calibration tasks and helps maintain the declared performance of precision balances. Using a certified reference mass improves process reliability and simplifies documentation for quality procedures.

Practical design that speeds up handling and reduces risk of error

The knob shape is engineered for secure handling during levelling and placement on balance pans, lowering the risk of handling errors and contamination. The compact profile, combined with a fine‑turned stainless steel surface, minimises surface dirt adherence and eases cleaning, supporting quick turnover in production environments where time and cleanliness matter.

Built for longevity: material choice and manufacturing quality

Manufactured from fine‑turned stainless steel, the mass resists corrosion and mechanical wear, ensuring long service life and less frequent re‑verification. The geometric accuracy achieved by the turning process reduces drift over repeated use, which translates into lower lifetime maintenance effort and stable calibration intervals for workshop and laboratory fleets.

Clear application guidance and accessory recommendation

Ideal for routine checks on analytical and precision balances, the weight is suitable for calibration tasks in quality control, toolrooms and service centres. Due to the narrow tolerance class, a protective case is recommended to preserve reference accuracy during storage and transport; Metav Werkzeuge can advise on compatible etuis and handling best practice to keep the reference mass within specification.
