Plasma Ball

A large, 8" diameter Plasma ball that looks fantastic in a darkened room.  The unit may be used for illustrating E=hv, capacitance effects, voltage breakdown of gases, differing energy states etc. Used with our technicians' friend tester you can demonstrate electric field strength.

A valuable addition to any science department and a real wow for open days.

Plasma Ball                                        £52.50

 

 Technicianís Friend            £7.34

A superb addition to the toolbox. Amongst other things, it allows for the checking of mains plug fuses without dismantling the plug, tests for breaks in mains cables, checks out 3cm wave apparatus, tests microwave doors for leakage and a 101 other things too numerous to mention.Essentially it is an electric field strength meter.

 

 

Resistance Substitution Box
