Contact spring made from phosphor bronze.
To mount on the rod of the magnet holder (470810).
Item No. 470820 is only the contact spring – for a complete setup, see 476000.
(Two 470820 are used in 476000.)
Provided with socket for safety plugs (shrouded banana plugs) – accepts standard 4 mm banana plugs as well.
Overall length: 140 mm. Spring dimensions: 8 x 0.5 x 100 mm.
The plastic part has a Ø 10 mm hole and a thumb screw.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
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.
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.
Allows students to measure angular velocity, acceleration, centripetal forces, and other full range of motion experiments.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Accurately measures position, velocity, and acceleration of a target. ScienceWorkshop version.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Determines the current through the sensor by measuring the voltage across the internal resistor.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
PASCO’s Light Sensor is ideal for indoor and outdoor relative light intensity experiments.
