[To all users]

• Easy to understand relationship between energy consumption and diameters of wires with visualized temperature.
• Easy to understand relationship between amount of electric current and diameter (thickness) of wire by feeling different handle’s resistance (heaviness) caused by different torque if “Gencon” (hand-held DC generator) is used for the power source.
• In combination with dry cell and meter(s), theoretically accurate result can be obtained.

[To teachers]

• Portable and versatile enough to combine with any type of electric circuit and/or meters including Narika’s “In-line type Digital Miniature Ammeter/Voltmeter” (A05-7060-W0/A05-7065-W0).

[To students]

• Easy to assemble with any other meter(s), as well as, a hand-held generator as the power source.

• Diameter of wires: φ0.2mm, φ0.4mm
• Length of each wire: 230mm
• Rated value: 3.0V, 1A
• Thermometer range: 16-36°C
