Useful for a variety of laboratory demonstrations, this 37Ω rheostat provides a variable resistance in electrical circuits. Oxidized constantan wire is wound on a vitreous enamelled tube. A sliding contact carriage, mounted on the slide bar, carries a phosphor bronze contact for long life. The rheostat has three binding posts with 4mm sockets for electrical connections: one at each end of the winding and another at the end of the slide bar.

• Resistance: 37Ω
• Maximum Current: 3.2A
• Eisco type PH1150K
