Ruhmkorff Coil produces pulses of high voltage spark from low voltage DC source (6 – 12 V DC). It is suitable for use with gas-filled discharge tubes, vacuum tubes, eudiometers and for general laboratory work. Includes an adjustable 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. Spark Length 15 mm.
