Product Description
Get audit-ready balance checks at the load points that matter with individual OHAUS ASTM calibration weights. This group covers 2 mg and 20 mg flats, 20 g and 200 g cylinders and 20 kg weights in knob-top and grip-handle styles. Every value is offered with no certificate, a traceable certificate or an ISO/IEC 17025 accredited certificate.
This listing is for OHAUS item number 30391077: ASTM Class 4 Calibration Weight, 2 mg, One-Piece, with Non-Accredited Calibration Certificate. Milligram flats are one-piece stainless steel, and gram and kilogram weights use two-piece construction with smooth, easy-to-clean surfaces. Class 1 and Class 4 tolerances are defined by ASTM E617, so you can pair the weight with the balance resolution you need to verify. Smaller weights ship in protective cases, while the 20 kg weights are supplied without a case for direct use on high-capacity scales. LIGHT LABS ships genuine OHAUS products and can help you match accessories and parts to your instrument.
