Cantz model, with mounted friction device; ready to use.
Sparks up to 40 mm long can be drawn from the large plate conductor into a fist-sized ball that is connected to the machine's friction holder. The discharge energy is around 100 mJ, which is significantly less than 350 mJ (millijoules). The transferred charge below 50 µC (microcoulomb). Both values at a relative humidity of 43% and a room temperature of 20 ° C.
The PVC drum has plexiglass end plates for an unobstructed view.
The effectiveness of the machine depends very much on the condition of the friction device (1 cm of foam and wool or cotton rags on it, washed and rinsed well with clear water), and whether all the insulated surfaces, drum including end surfaces and plexiglass supports have been wiped off with alcohol . Oil the bearings from time to time. The machine was developed and tested under German climatic conditions. Please note that we therefore only offer a statutory warranty of 2 years within Europe.
Base board 50 x 55 cm, height 56 cm, drum diameter 31 cm.
