Alloy 8, high grade stainless steel calibration weights and reference standards. NVLAP, NIST Traceable calibration certificates in UltraClass Series and ANSI/ASTM Class 000, 00, 0, 1, 2, 3, and 4.

• Range: 1 mg to 50 kg, 1 mg to 500 mg
• Style: Cylindrical, flat, wire
• Density: 1 g and above: 8.03 g/cm³; 500 mg to 5 mg: 7.95 g/cm³; 5 mg and below: 2.70 g/cm³

Weights and weight sets are manufactured with the finest stainless steels available, including Troemner's proprietary Alloy 8. Specification on surface finish, markings, construction, material density, and magnetic properties become more restrictive as the weight tolerances decease in order to enable the weight to maintain its tolerance over time.
