Rubber Hammer, Medium

Description :-
Simple, innovative kit allows you to perform a number of experiments on vacuum and air pressure. The kit clearly demonstrates the method by which a pump works. Also illustrates that air has mass and helps find its mass and density. Explain the effect of surrounding air pressure on a sealed balloon. The balloon will expand when the surrounding air is removed. And also demonstrate that liquid boils at reduced temperature when the surrounding air pressure is reduced with instructions.

Description :- Stroboscopic flashes are triggered by either the internal oscillator or by external pulses which may be connected to the two 4mm sockets mounted on the rear panel of the instrument. Example of the many applications of this unit are to be found in motion analysis multi exposures photography, examination of moving parts and measurement of rotational speed. Specifications:- Input Volts : 220V AC, 50 Hz Flash Rate: 0- 9999 Flashes per minute. Resolution : 1 Display: 7 Segment LED (4 nos.)
