Adam Equipment ASTM 3 - 1g Stainless Steel Calibration Weight, 1g, ASTM Class 3

Adam Equipment ASTM 3 – 1g Stainless Steel Calibration Weight, ASTM Class 3

The Adam Equipment ASTM 3 – 1g individual calibration weight delivers reliable, traceable accuracy for testing and calibrating precision balances. Manufactured from polished stainless steel and conforming to ANSI/ASTM E617 Class 3 tolerances, this 1 g weight is a dependable reference mass for laboratory and industrial environments where consistent measurement results matter. It is sold individually, allowing users to acquire exactly the denomination they need.

Key Features

• Polished stainless steel construction provides lasting durability and resistance to surface corrosion
• Supplied in an impact-resistant plastic case that protects the weight during storage and transport
• Meets ANSI/ASTM E617 Class 3 requirements for general-purpose precision calibration
• ASTM 2–4 weights feature a 7.9 g/cm³ density, consistent with the standard stainless alloy specification
• Serial number clearly recorded on the case for full calibration traceability
• Available across ASTM classes 0 through 4 to match a wide range of balance accuracy requirements

Detailed Overview

At 1 g, this ASTM Class 3 weight occupies the lighter end of the gram-denomination range and is particularly well-suited for calibrating balances with milligram-level readability. ASTM Class 3 sits in the mid-range of the ASTM hierarchy — it offers reliable calibration for most general-purpose precision balances while remaining below the tighter tolerances required by Classes 0, 1, and 2 for more demanding analytical applications. The polished stainless steel surface minimises surface contamination and simplifies cleaning between calibration cycles, helping to maintain accurate mass values over extended periods of use.

Each weight is sold individually, allowing laboratories and calibration teams to build a custom set that precisely matches their programme requirements without purchasing denominations they do not need. The included plastic case ensures the weight is protected from surface damage and environmental exposure between use, and the recorded serial number keeps traceability documentation straightforward and organised.

Applications

• Routine calibration and verification of laboratory precision balances
• Quality control checks in pharmaceutical and chemical research environments
• Calibration of balances used in educational and teaching laboratories
• Reference mass for testing scales in light manufacturing and production settings
• Compliance verification against ANSI/ASTM E617 Class 3 standards
