Induction Coil, Spark in 15mm Material_LDPE the standard spectrometer integrates collimatorThe traditional induction coil capable of producing a spark with an input of 6 to 12 V DC and is therefore ideal for use with vacuum tubes, eudiometers etc. A fully adjustable vibrator system is incorporated and spark suppression capacitors are housed in the base. A pair of pointer electrodes are supplied with the instrument. Pointer electrode have an insulating handle for adjustment of the spark gap. Low voltage input is via a pair of mounted 4 mm
