Precision ASTM Class 2 Calibration Weight — ASTM 2 - 1000g (1 kg)

The Adam Equipment ASTM 2 - 1000g is an individual 1 kg calibration weight conforming to ANSI/ASTM Class 2 tolerances, designed for precision balance calibration and routine quality-control verification. Positioned in the mid-accuracy range of the ASTM E617 classification system, Class 2 weights balance measurement accuracy with broad laboratory applicability, making them a practical choice for formulation, QA testing, and applied analytical work. The polished stainless steel construction provides long-term corrosion resistance and reliable dimensional stability across regular use.

Key Features

• Polished stainless steel body produced to ANSI/ASTM Class 2 tolerance specifications
• 7.9 g/cm³ steel density meeting ASTM E617 Class 2–4 material requirements
• Individually serialised weight; serial number recorded on the supplied protective case
• Supplied in an impact-resistant hard plastic case for safe storage and transport
• Meets ANSI/ASTM E617 Class 2 requirements for precision balance calibration
• Available across Classes 0–4 and multiple nominal values to suit a range of calibration needs
• Smooth surface finish supports easy cleaning and visual contamination inspection

Detailed Overview

Built to ANSI/ASTM E617 Class 2 dimensional and tolerance specifications, this 1 kg stainless steel weight provides consistent, repeatable mass values appropriate for precision balances typically operating at readabilities of 0.01 g or finer. The 7.9 g/cm³ density meets the material specification for ASTM Classes 2 through 4 and, combined with the polished surface finish, reduces particulate accumulation during normal laboratory handling. Class 2 is a widely specified tolerance class for mid-level precision work, including formulation, compounding, and routine quality assurance balance verification.

Every weight in Adam Equipment's ASTM series ships in its own hard plastic case, with the unique serial number printed or engraved on the case exterior. This approach allows laboratories to quickly match a weight to its calibration documentation without relying solely on the weight itself, which is practical in environments where multiple weights of similar nominal values may be in use simultaneously. The case provides physical protection against impact damage and contamination between calibration events, helping to extend the weight's functional service life.

Within Adam Equipment's ASTM calibration weight family, which spans Classes 0 through 4 and a broad range of nominal values, the Class 2 range occupies the position between the tighter-tolerance Class 0 and 1 weights and the more general-purpose Class 3 and 4 offerings. This makes the 1 kg Class 2 weight a sound choice for laboratories whose balances and measurement requirements sit in the middle of the ASTM accuracy spectrum. Routine cleaning with lint-free cloths and storage in the supplied case will maintain the weight's surface and mass stability between calibration intervals.

Applications

• Calibrating precision balances in pharmaceutical, chemical, and food science quality laboratories
• Formulation and compounding verification in manufacturing environments
• Balance performance checks during routine equipment qualification activities
• Multi-point calibration protocols at 1 kg on precision analytical balances
• Educational and research institutions specifying ANSI/ASTM Class 2 calibration standards
• General laboratory balance verification where Class 2 tolerances are required by procedure

Why Choose the Adam Equipment ASTM 2 - 1000g?

The Adam Equipment ASTM 2 - 1000g gives precision laboratories a cost-effective route to ANSI/ASTM Class 2 compliance backed by polished stainless steel construction, individual serialisation, and a protective hard case. The 7.9 g/cm³ steel density and smooth finish maintain accuracy and cleanliness across regular use, while the case-mounted serial number simplifies traceability record-keeping under ISO, GLP, and other quality systems. For laboratories that require reliable Class 2 mass standards at 1 kg without the tighter specifications — and associated cost — of Class 0 or 1 weights, this unit offers a well-matched, practical solution.
