Free Fall Apparatus Timer

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 micro switch 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, the lid moves down and activates the micro switch to turn off the timer. GFF/SET comes complete with Laboratory Timer code: EDU096. The Laboratory Timer has an in-built power supply for the electromagnet in the G by Free Fall apparatus.
