Adam Equipment ASTM 1 1g - 200g Calibration Weight Set

An ASTM Class 1 weight set is used for high-precision calibration of analytical and precision balances. It ensures that your weighing equipment meets strict accuracy standards and provides traceable, repeatable measurement results in laboratory and industrial environments.

This set includes a complete range of calibration weights such as 1 g, 2 g (x2), 5 g, 10 g, 20 g (x2), 50 g, 100 g, and 200 g (often x2). This variety allows users to test multiple calibration points across a scale’s full range.

ASTM Class 1 weights offer tight tolerance limits and high accuracy, making them ideal for calibrating analytical and precision balances with fine readability. They provide a strong balance between professional accuracy and cost compared to higher classes.

These weights are manufactured from highly polished stainless steel, which provides corrosion resistance, low magnetic susceptibility, and long-term stability. This ensures reliable calibration performance over time.

The set typically comes with a protective carrying case, cotton gloves for safe handling, and labeled storage slots. These features help prevent contamination, maintain accuracy, and extend the lifespan of the weights.
