Adam Equipment ASTM 4 1g - 200g Calibration Weight Set, 1g-200g Range, ASTM Class 4

Adam Equipment ASTM Class 4 Calibration Weight Set — 1g to 200g for Bench and Portable Scales

The Adam Equipment ASTM Class 4 calibration weight set provides 1g to 200g of reference masses for verifying bench scales, top-loading balances, and compact portable weighing devices where Class 4 tolerance is specified. Constructed from stainless steel and meeting ANSI/ASTM E617 standards, this cost-effective set is the appropriate choice for general-purpose calibration in workshop, retail, and light industrial environments that do not require the tighter tolerances of Class 1 or 2.

Key Features

• ASTM Class 4 tolerance appropriate for bench scales, top-loading balances, and compact portable scales
• 1g to 200g coverage for a concise range of calibration points covering the lower capacity region
• Stainless steel construction provides corrosion resistance and durability through regular use and handling
• ANSI/ASTM E617 compliant for traceable, standards-documented calibration records
• Cotton gloves included to protect weight surfaces from contamination during handling
• Individual weight denominations from 1g to 200g for stepwise, incremental scale verification
• Economical Class 4 option for calibration programs where analytical-grade tolerances are not required

Detailed Overview

ASTM Class 4 calibration weights are positioned in the classification system for applications where reliable, cost-effective reference masses are needed to verify instruments operating at bench-scale or portable-scale accuracy levels. The 1g to 200g range is well suited to compact balances and bench scales with capacities in the lower portion of the gram range, providing calibration points that cover the instrument's linearity from its lightest measurable increment through the 200g reference. Each denomination is produced to Class 4 tolerances, ensuring the set supports accurate and consistent calibration results for the target instrument types.

The stainless steel material ensures the weights maintain their physical integrity through regular use in workshop, warehouse, or general laboratory environments. The compact 200g upper limit makes this set easy to transport when calibration technicians service multiple scales across a facility. Pairing this set with instruments of appropriate readability and capacity ensures that the Class 4 tolerances are suitable for the verification task at hand.

Applications

• Bench scale calibration in light manufacturing, packaging, and assembly environments
• Compact and portable balance verification for field calibration technicians
• Classroom and educational laboratory weighing equipment maintenance
• Retail counter scale verification for lighter commodity categories
• General-purpose quality control weight checks in production facilities

Why Choose the Adam Equipment ASTM Class 4 1g–200g Set?

When the application calls for dependable, ANSI/ASTM E617 traceable calibration without the added cost of higher-class weights, this Class 4 set is a sound and practical choice. Its stainless steel construction withstands the handling demands of active calibration programs, and the focused 1g to 200g range covers the most common calibration requirements for bench and compact portable scales. Cotton gloves are included to help maintain weight cleanliness and preserve accuracy across repeated calibration cycles.
