Cast Iron Slotted Weights are used in a variety of applications such as pressure, torque, and tensile strength testing. Slotted Weights are typically used with a hanger that also has itsweight calibrated so the hanger can be used as part of the overall weight under test.
Material: Cast iron
Class: M1
Density: 7.0g/cm³
For testing or calibrating weighing equipment with a division size of 1g or more, or for proof load testing
The weights have a slot to fit in value according to need
