(HYGRADE) High Voltage Induction Coil Manufacturer 25mm,50mm,100mm Spark Gap

Induction Coil has a 25mm / 1" spark gap and can produce pulses of high voltage current from a low voltage direct current source such as a battery. It is suitable for use with gas-filled discharge tubes, vacuum tubes, eudiometers and for general laboratory work. It is comprised of two coils fully enclosed in a polished wooden case with binding posts. Includes an adjustable neef type vibrator system, primary current polarity reversal, on-off switch, a capacitor enclosed in the box and special alloy contacts. Spark gap at the discharge points can be adjusted by sliding rods back and forth. Input: 6-12 Volts DC at 3 Amps max.

Note---we have various models of induction coil with Spark Gap from 25mm to 100mm.
