Advantages:

• The E1 class tolerance ensures extremely high precision for calibration of the most accurate balances.
• A broad range of weight values from 2 kg down to 1 mg allows for versatile calibration applications across different scales and balances.
• One-piece construction and high-density materials enable long-term stability and resistance to wear, preserving calibration integrity.
• The inclusion of a protective case ensures safe transport and minimizes contamination or damage to weights.
• Material variation optimizes durability and handling: aluminum for smallest weights reduces weight damage risk, while alloy and stainless steel provide stability for larger weights.
