Holder for loose Ø 50 mm lenses and 50 x 50 mm apertures.
The 80 x 72 mm shielding plate incorporates a spring-loaded holder for lenses and apertures from 1 to 16 mm thick.
Excl. saddle.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
This system is ideal for hands-on experimentation with basic circuits and includes more components than the Basic Set, as well as sensors. It is a component of the Essential Physics program.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
Replacement test coupons for the Stress/Strain Apparatus.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
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.
