Adam Equipment ASTM 2 - 100g Calibration Weight, 100g Capacity, ASTM Class 2, Stainless Steel

Adam Equipment ASTM 2 Individual Calibration Weight, 100 g Precision Stainless Steel

The Adam Equipment ASTM 2 100 g calibration weight is a polished stainless steel individual weight meeting ASTM Class 2 tolerance specifications. Suited to precision balance calibration across a broad range of laboratory, pharmaceutical, and industrial quality assurance applications, it delivers a reliable mid-class calibration reference at the widely used 100 g denomination.

Key Features

• 100 g nominal value covering the mid-range calibration span of most bench-top precision balances
• ASTM Class 2 conformance, meeting the defined ANSI/ASTM tolerance limits for this class
• 7.9 g/cm³ density as specified for ASTM Class 2-4 weights
• Polished stainless steel body for long-term corrosion resistance and surface cleanliness
• Individual impact-resistant plastic case included for protected storage and transport
• Serial number recorded on case for calibration documentation and traceability

Detailed Overview

ASTM Class 2 occupies the middle tier of the ASTM weight classification system, offering calibration accuracy appropriate for precision balances used in general laboratory work, pharmaceutical production, and industrial quality control where the highest-class tolerances of Classes 0 or 1 are not required by the calibration standard. The 100 g denomination is one of the most practical and widely specified calibration references — it falls comfortably within the working range of most bench-top precision balances and is suitable for span calibration at mid-range capacity.

Each 100 g ASTM 2 weight is manufactured to the 7.9 g/cm³ density specification and finished to a polished surface that minimises the risk of mass variation caused by surface contamination or oxidation building up over time. The individual impact-resistant plastic case provides essential protection during storage and transport, preventing physical damage that could compromise the weight's tolerance compliance. The serial number displayed on the case supports the formal calibration record-keeping requirements of ISO-accredited laboratories, quality management systems, and pharmaceutical GxP documentation standards.

Applications

• Span calibration of precision and analytical balances in laboratory settings
• Industrial quality assurance balance verification and routine performance testing
• Pharmaceutical production weighing reference and release testing compliance
• Formal calibration record management in quality-managed laboratory environments

Why Choose the Adam Equipment ASTM 2 - 100g?

The 100 g ASTM 2 weight provides an accurate and traceable calibration reference for precision balance users who require ANSI/ASTM compliance without the cost premium of Class 1. Its protective plastic case, serialised identification, and polished stainless steel construction combine to make it a dependable long-term calibration tool. It is part of the complete Adam Equipment ASTM individual weight range, enabling matched sets to be assembled across multiple denominations and classes as needed.
