2 kg Calibration Weight, Button Shape, Stainless Steel Fine-Turned, OIML Class M1, 100 mg Tolerance - KERN

Product information "2 kg Calibration Weight, Button Shape, Stainless Steel Fine-Turned, OIML Class M1, 100 mg Tolerance - KERN"

Reliable traceable reference for precise scale verification thanks to OIML M1 accuracy and a robust fine‑turned stainless steel finish; ideal where repeatable mass standards are required. Order the KERN 347-12 directly via Metav Werkzeuge or ask our consultants if needed.

KERN 347-12 calibration weight — OIML M1, 2 kg, stainless steel

The KERN 347-12 offers a compact, knob‑style calibration weight designed for verification and routine checks of laboratory and industrial scales.

  • OIML class M1 for high-precision checks
  • Nominal mass 2 kg with 100 mg tolerance
  • Fine-turned stainless steel construction
  • Knob form for safe handling and positioning

Reliable reference for consistent measurement results

A certified calibration weight in OIML M1 delivers a stable reference for repeatable verifications. With a nominal mass of 2 kg and a declared tolerance of 100 mg, this standard provides measurable assurance when validating balances or performing routine control checks. The defined tolerance supports clear decision thresholds for adjustments and repairs, reducing downtime and supporting quality control workflows in production and laboratory environments.

Robust design that simplifies handling and storage

The combination of fine‑turned stainless steel and a knob form gives the mass both corrosion resistance and ergonomic handling. The turned finish minimises surface irregularities that could trap contaminants, while the knob facilitates secure placement on pans and reduces the risk of accidental contact. This design choice prolongs service life and keeps handling errors to a minimum, contributing to reliable daily operation in workshops and test rooms.

Conformity and calibration guidance for long-term traceability

EC type approval for calibration weights will no longer be possible from 30 November 2025; therefore a DAkkS calibration is recommended for enduring legal and metrological traceability. A DAkkS certificate ensures national traceability chains and is accepted for most auditing and regulatory needs. Supplied from Germany, this standard mass supports documented traceability that is essential for accredited measurement routines and supplier quality agreements.

For traceable verification with a trusted brand, request the KERN 347-12 through Metav Werkzeuge or consult our advisors for DAkkS calibration and delivery from Emmerich.

FAQ

What does OIML M1 mean for routine verifications? OIML M1 denotes a high-precision class; the KERN 347-12 meets this classification and is suitable as a reference for routine balance checks where a 100 mg tolerance is acceptable.

Can this mass be used on workshop and laboratory scales? Yes, the 2 kg nominal mass and robust stainless steel construction make the weight appropriate for both industrial scales and laboratory balances, provided the balance capacity and accuracy class are compatible.

How should the weight be handled to avoid errors? Handle the weight by the knob form and use clean gloves or tweezers; secure placement on a level pan minimises centre‑of‑gravity shifts and reduces handling-related deviations for the KERN 347-12.

Is an EC type approval available for this weight? EC type approval for calibration weights will not be possible from 30 November 2025; instead, a DAkkS calibration is recommended to maintain traceability and audit acceptance for the KERN 347-12.

How precise is the KERN 347-12 for calibration tasks? The declared tolerance is 100 mg for the 2 kg nominal mass, providing a reliable reference for control checks and routine verifications.
