Induction Coil 50mm spark

The traditional induction coil capable of producing a spark with an input of 6 - 12v DC and is therefore ideal for use with vacuum tubes, eudiometers etc. A fully adjustable vibrating system is incorporated with spark suppression capacitors in the base. A pair of pointer electrodes is supplied with the instrument, the pointer electrode having an insulating handle for spark gap adjustment. Low voltage input is via a pair of baseboard mounted 4mm sockets.

The spark length of 2.5 - 5 cm depends on humidity. A 2 cm spark induction coil is also available.
