Chrome-Plated Lab-Grade Calibration Set

This calibration set comprises five individually specified weights: 1 g, 2 g, 5 g, 10 g and 20 g. All are made from chrome-plated material, resulting in a reflective, silvery-white surface that remains visually consistent and easy to clean. Mass accuracy is guaranteed at ±0.003 g per unit. Physical dimensions increase progressively: 1 g (0.5 × 0.5 × 0.8 cm), 2 g (0.6 × 0.6 × 1.1 cm), 5 g (0.9 × 0.9 × 1.7 cm), 10 g (1.3 × 1.3 × 1.5 cm), 20 g (1.5 × 1.5 × 2 cm). Dimensional tolerance is ±1–3 mm. The set contains exactly one of each weight — no duplicates or extras — and weighs precisely 38 g in total. No additional packaging mass is indicated.
