Set of 8 rods. Used for specific gravity experiments and so forth. Made from aluminium, lead, nylon, glass, rubber, iron, copper and brass.
Supplied in a plastic box with a clear lid. Rod length: 102 mm.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
