Adam Equipment ASTM 2 1g - 200g Calibration Weight Set, 1g-200g Range, ASTM Class 2

Adam Equipment ASTM Class 2 Calibration Weight Set — Precision 1g to 200g for Laboratory Balances

The Adam Equipment ASTM Class 2 calibration weight set covering 1g to 200g delivers a precision reference kit for laboratory and production precision balance calibration in the sub-200g range. Produced from stainless steel at 7.9 g/cm³ and complying with ANSI/ASTM E617, this set provides accuracy positioned between Class 1 analytical-grade and Class 4 general-purpose specifications, making it the correct choice for precision balances used in pharmaceutical, jewelry, and research applications where milligram-level readability requires a corresponding calibration reference standard.

Key Features

• ASTM Class 2 precision for calibrating precision laboratory and production balances with milligram or finer readability
• Compact 1g to 200g coverage matched to balances operating primarily below the 200g threshold
• Stainless steel at 7.9 g/cm³ for stable, corrosion-resistant reference masses in laboratory environments
• ANSI/ASTM E617 compliant for traceable calibration documentation supporting quality audits
• White cotton gloves included to prevent surface contamination from fingerprint oils during handling
• Individual weight denominations from 1g to 200g for stepwise precision balance linearity verification
• Compact set storage for controlled-environment cabinet or safe storage between calibration intervals

Detailed Overview

The 1g to 200g Class 2 set is designed for precision balances whose capacity and readability fall between the domains of high-resolution analytical instruments and general-purpose bench scales. At ASTM Class 2 tolerance, each weight piece is accurate enough to verify precision balances used in pharmaceutical preparation, jewelry manufacturing, environmental sample preparation, and research chemistry where readability is in the milligram range and calibration must be traceable to a recognized standard without necessarily requiring the very tightest Class 1 tolerances.

The stainless steel material at 7.9 g/cm³ provides resistance to the mild chemical and environmental conditions encountered in precision laboratory and light production settings. The 200g maximum denominator is appropriate for smaller precision balances commonly used in quality control, recipe formulation, and specialty weighing applications. Each denomination provides a specific calibration reference point, and the complete set from 1g to 200g gives the calibration technician the data needed to verify the balance's linearity and accuracy across its working range.

Applications

• Precision balance calibration in pharmaceutical development and quality control laboratories
• Jewelry, precious metal, and gemstone balance verification for trade and manufacturing
• Research laboratory balance routine maintenance and performance verification
• Environmental sampling and laboratory testing balance calibration programs
• Food science, nutrition analysis, and formulation precision balance checks

Why Choose the Adam Equipment ASTM Class 2 1g–200g Set?

Where ASTM Class 4 tolerances are insufficient for the balance readability and Class 1 analytical-grade precision is not mandated by the application, this Class 2 set provides an accurately positioned calibration solution. The sub-200g range makes it a focused, compact kit for laboratories with precision balances in this capacity range, and the stainless steel construction supports long-term durability through regular calibration intervals. Cotton gloves complete the kit for immediate, contamination-free deployment.
