Product Description
Build up any test load you need, one stackable piece at a time. These OHAUS cast iron slotted weights and calibrated weight hangers let you assemble large loads quickly for scale checks, force demonstrations and teaching labs without buying a dedicated weight for every value.
This listing is for OHAUS item number 83040499: Cast Iron Slotted Weight, 1/2 lb, ASTM Class 7, One-Piece, with Accredited Calibration Certificate. Each weight is made from dense cast iron with a slot that drops over the hanger rod, and the hangers combine a stainless steel rod with a cast iron base. Hangers are calibrated so their own mass counts toward the total load under test. Choose ASTM Class 5, 6 or 7 or NIST Class F tolerance, and order with an accredited calibration certificate, a non-accredited certificate or no certificate, depending on your quality system. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
Key Features
- Stackable Slotted Design – the slot fits over a hanger rod so several weights can be combined into one load
- Calibrated Hangers – the hanger's mass is part of the stated value, so it counts toward the total weight under test
- Durable Cast Iron Body – dense, economical material suited to heavy everyday handling
- Choice of Tolerance Class – available in ASTM Class 5, 6, 7 or NIST Class F to match the required accuracy
- Flexible Certification – order with an accredited calibration certificate, a non-accredited certificate or no certificate
