OIML M1 Cast-Iron Block & Eco-Block Test Weights – 5 kg to 50 kg

Choose from a range of high‑quality OIML M1 cast‑iron test weights available individually from 5 kg to 50 kg. Offered in two versions—standard machined block (346‑86 to 346‑89) and economical Eco‑Block (346‑76 to 346‑79)—these weights deliver precision calibration for scales and balances used in industry, laboratories, and manufacturing.

Key Features

  • Class M1 Accuracy: Certified tolerances of ±250 mg (5 kg) up to ±2.5 g (50 kg)
  • Machine-Finished vs Eco Finish: Standard block has machined surfaces for improved stability; Eco‑Block is lacquered cast iron with a practical unmachined finish
  • Solid Cast-Iron Construction: Durable, stable block shape ideal for industrial calibration
  • Sold Individually: Ideal for supplementing existing sets or replacing lost weights
  • Made in Germany: Precision-manufactured by KERN for reliability and longevity
