ASTM Calibration Weights / Weight Sets; Class 4
With a choice of sizes and combinations, Adam Equipment's weights simplify external calibration on precision balances. Weights are packaged in sets or individually and are crafted of highly polished stainless steel. ASTM weights are available in classes 0-4, meeting the requirements of ANSI/ASTM.
ASTM weight sets include a complete group of test weights that can meet requirements for testing to ASTM standards. Class 0 weights are designed for metrology laboratories. Class 1 and 2 weight sets provide a high level of accuracy and are ideal for calibrating analytical and precision balances. Class 4 weight sets offer a lower level of accuracy but are affordable and ideal for calibrating compact portable balances and bench scales.
