Product code: GFF/SET
Out of stock
The apparatus consists of an electromagnet housed in a plastic moulded case supplied with a heavy steel sphere, an electromagnet unit with connections for an external timer and a platform unit containing a microswitch and terminals for the external timer. Action: The sphere is released by moving the switch on the electromagnet to the upward position. This action simultaneously starts the timer. As the sphere hits the cork mat on the platform unit it activates a microswitch to turn off the timer. It is recommended that this be used in conjunction with the Laboratory Timer (code: EDU096) which has an in-built power supply for the electromagnet, or both can be purchased together as a combined set (code: GFF/SET).
