Cast Iron Class M Calibration Weight
Product Overview

A Cast Iron Class M Calibration Weight is a moderately accurate mass standard made from cost-effective cast iron, protected by paint or lacquer against rust. It features handling aids (knob/recess) and clear markings, including its Class M designation and nominal value.

Key Advantages: Economy (especially for larger masses) and suitability for calibrating commercial and industrial scales.
Limitations: Susceptibility to corrosion (if coating damaged), magnetic properties, brittleness, and lower accuracy compared to stainless steel weights in Classes F or E.
