Product Description
When a balance check has to stand up to an auditor, a single well-characterized reference mass is often all you need. These two-piece ASTM individual weights from OHAUS are offered in Class 1 for high-precision work and Class 4 for routine verification, in 70 g, 80 g, 600 g and 8 kg values, so you can match the test load to the instrument you are actually checking.
This listing is for OHAUS item number 30391164: ASTM Class 4 Calibration Weight, 8 kg, Two-Piece Grip Handle, EB, with Non-Accredited Calibration Certificate. The 70 g, 80 g and 600 g values are straight cylinders machined from 316 stainless steel and supplied with a protective case, while the 8 kg value uses a grip-handle design in 303 stainless steel for safer lifting. Two-piece construction allows the mass to be adjusted during manufacture and recalibration. Each value can be ordered with no certificate, a traceable non-accredited certificate, or an ISO/IEC 17025 accredited calibration certificate, and the weights are made in the USA. LIGHT LABS ships genuine OHAUS products and can help you match accessories and parts to your instrument.
Key Features
- ASTM Class Choice – Class 1 tolerances for high-precision balances down to 0.1 mg readability, or Class 4 for general laboratory and production checks
