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 vibration 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 1 - 2 cm depends on humidity.
A 5 cm spark induction coil is also available.
