Adam Equipment ASTM 2 1g - 500g Calibration Weight Set, 1g-500g Range, ASTM Class 2

Adam Equipment ASTM Class 2 Calibration Weight Set — 1g to 500g for Precision Balance Calibration

The Adam Equipment ASTM Class 2 calibration weight set covering 1g to 500g is engineered for precision balance calibration in laboratories and production facilities where Class 2 tolerances are appropriate. Produced from stainless steel at 7.9 g/cm³ and conforming to ANSI/ASTM E617, this set occupies the practical middle tier of the ASTM classification system, offering greater precision than Class 3 and 4 general-purpose weights without the higher cost of Class 1 analytical-grade references.

Key Features

• ASTM Class 2 tolerance — suited to precision balance calibration in quality laboratories and regulated production
• 1g to 500g range provides comprehensive verification coverage for a wide span of precision balance capacities
• Stainless steel at 7.9 g/cm³ for durable, stable, corrosion-resistant reference masses
• ANSI/ASTM E617 compliant for documented, traceable calibration records supporting audit requirements
• White cotton gloves included to protect weight surfaces from contamination during handling
• Complete set of individual denominations from 1g through 500g for thorough balance linearity verification
• Appropriate for GMP and quality management system calibration programs requiring intermediate tolerance levels

Detailed Overview

ASTM Class 2 weights represent a well-balanced choice for routine laboratory and industrial precision balance calibration. They provide higher accuracy than the Class 3 and 4 weights used for bench and general-purpose scale verification, yet remain more cost-effective than the Class 1 sets required for calibrating analytical instruments at the very highest readability levels. For precision balances used in pharmaceutical preparation, environmental testing, and food science, Class 2 is frequently the specified tolerance level.

The stainless steel material at 7.9 g/cm³ provides corrosion resistance and physical durability that holds up under the regular handling expected in a facility-wide calibration program. The 1g to 500g spread gives calibration technicians sufficient reference points to verify balance performance across a meaningful portion of the instrument's operating range, supporting comprehensive verification of linearity, repeatability, and accuracy at multiple points within the capacity span.

Applications

• Routine calibration of precision balances in quality control and research laboratories
• Pharmaceutical production and formulation equipment verification programs
• Food science, nutrition analysis, and beverage production balance calibration
• Environmental monitoring and materials testing balance maintenance
• Industrial production weighing equipment verification where Class 2 is specified

Why Choose the Adam Equipment ASTM Class 2 1g–500g Set?

For environments where precision balance accuracy is required and Class 2 tolerances are appropriate, this set provides a dependable, ANSI/ASTM E617 traceable calibration solution. The stainless steel weights resist wear through repeated use in active calibration programs, and the comprehensive 1g to 500g range supports thorough balance verification without needing multiple smaller sets to cover the full capacity span. Cotton gloves ensure the weights remain uncontaminated for consistent performance over an extended service life.
