Adam Equipment ASTM 4 1g - 500g Calibration Weight Set, 1g-500g Range, ASTM Class 4

Adam Equipment ASTM Class 4 Calibration Weight Set — 1g to 500g for Mid-Range Scale Verification

The Adam Equipment ASTM Class 4 calibration weight set in the 1g to 500g range provides a mid-span reference kit suited to bench scales, portable balances, and compact weighing instruments operating within the 500g capacity range. Stainless steel construction and compliance with ANSI/ASTM E617 make this a reliable, traceable calibration solution for general-purpose verification tasks in industrial, retail, and light laboratory environments.

Key Features

• 1g to 500g range for thorough verification of mid-capacity bench scales and portable balance models
• ASTM Class 4 tolerance appropriate for general-purpose weighing equipment calibration without over-specifying precision
• Stainless steel weights resist corrosion and physical wear through repeated handling in active calibration programs
• ANSI/ASTM E617 compliant for documented, traceable calibration records supporting audit and quality programs
• Cotton gloves included to maintain weight surface cleanliness during handling and storage
• Full range of denominations from 1g to 500g enables incremental linearity verification of the instrument
• Compact and portable for facility-wide calibration programs covering multiple instrument locations

Detailed Overview

The 1g to 500g Class 4 set occupies a practical mid-range position in Adam Equipment's ASTM weight offering, providing broader coverage than the 1g to 200g set while remaining more manageable than the full 1g to 1kg kit. For bench and portable scales with a 500g upper capacity, this set provides calibration points across the instrument's full operating range, supporting verification of both low-end linearity and upper-capacity accuracy. Each denomination is fabricated to ASTM Class 4 tolerances, giving calibration technicians a consistent reference from the lightest gram-increment through the 500g upper reference.

In facility-wide calibration programs where instruments span a range of capacities, the 500g upper limit makes this set suitable for a broad group of bench and portable instruments without the additional storage and handling requirements of a 1kg set. The stainless steel construction is appropriate for routine use in workshop and laboratory environments, maintaining its dimensional integrity through the environmental conditions and handling frequency typical of scheduled calibration intervals throughout the year.

Applications

• Bench scale calibration up to 500g in production, packaging, and light industrial environments
• Portable and pocket balance verification for field calibration and laboratory use
• Retail counter scale verification for lighter product and commodity categories
• Laboratory balance routine verification for instruments in the 500g capacity range
• Industrial quality control weight checks where Class 4 tolerance is the specified standard

Why Choose the Adam Equipment ASTM Class 4 1g–500g Set?

This 1g to 500g Class 4 set provides a cost-effective, standards-compliant calibration kit for operations whose bench and portable scales fall within this capacity range. The durable stainless steel weights maintain their physical integrity through many calibration cycles, and the complete 1g to 500g denomination range supports a thorough instrument verification process. Supplied with cotton gloves, the set is ready for immediate use and designed to support reliable, repeatable calibration results over an extended service life.
