Product Description
Confident balance calibration starts with mass standards whose class and certification match the job. These OHAUS ASTM calibration weight sets and two-weight CalPak kits deliver Class 1 and Class 4 tolerances in protective cases, with no certificate, non-accredited or ISO/IEC 17025 accredited certification options.
This listing is for OHAUS item number 80859549: ASTM Class 1 CalPak Calibration Weight Kit, 200 g and 10 g, with Accredited Calibration Certificate,. Gram weights are two-piece stainless steel alloy construction, while milligram weights are one-piece stainless steel, with aluminum used below 5 mg in the fractional sets. Class 1 serves as a primary reference for calibrating high-precision balances with readability down to 0.1 mg and for maintaining traceability to lower-class weights, while Class 4 suits routine checks of precision and toploading balances. Handle weights with gloves or forceps and store them in the case to protect their calibrated values.
