Chain Drive with Tensioner Mechanical Demonstration Model Subcategory_Filtration Equipment Five-ohm reference coil non-inductively wound

Five-ohm reference coil non-inductively wound from double silk-covered constantan inside a transparent tube

showing liquid-convection currents as heat applied at one corner circulates colored dye

sized to detect bidirectional milliampere currents in induction

the lower-resistance higher-current option in the compact-tube rheostat line
