Tuning fork set with 8 x different frequencies: 256, 288, 320, 341.3, 384, 426.6, 480, 512 Hz.
Each set can be stored in the included plastic box (325 x 265 mm).
The forks vary in length: 95 mm – 145 mm.
Replacement test coupons for the Stress/Strain Apparatus.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Determines the current through the sensor by measuring the voltage across the internal resistor.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
