Pen plating requires precise, micro-amperage control, and this machine provides just that so you can achieve the best results. This sturdy system features micro-amp voltage with an LED voltmeter. Its analog dial controls range from 10/100 to 100/100 (or 1 amps). You can achieve the exact voltage you need when doing rhodium pen plating and for doing gold pen plating. This Pen Plater is constructed from a heavy-gauge steel, and measures approximately 7″ wide x 8″ deep x 3″ tall. The set includes the machine, glass jars for storing pen plating solutions, a standard wire platinum anode plating pen, and one clamp with with an alligator clip.
