Product Description
Keep calibration intervals on schedule by stocking the exact OHAUS ASTM weight values your balances need. This range covers 1 mg to 200 mg flats, 2 g and 160 g cylinders, and heavy 1,500 g, 2 kg and 16 kg weights, so both microbalance checks and bench-scale tests are covered. Certificate choices let you balance documentation needs against budget.
This listing is for OHAUS item number 30391135: ASTM Class 4 Calibration Weight, 16 kg, Two-Piece EB Grip Handle, No Certificate. Milligram values are one-piece stainless steel flats, while gram and kilogram values are two-piece weights in knob-top, straight cylindrical or grip-handle form; the 16 kg grip-handle weights ship without a case. Tolerances are defined by ASTM E617 for Class 1, Class 2 or Class 4, and accredited versions include an ISO/IEC 17025 certificate. Handle smaller pieces with tweezers and larger pieces with gloves or lifting aids to protect surface finish and mass value. Add it to your LIGHT LABS order and keep your lab running with genuine OHAUS equipment.
