Coefficient of Copper Apparatus, Cold at 20 ohms

The Coefficient of Copper Apparatus consists of a heat-resistant resin tube wound with a delicate enamelled copper wire. The wire's termination connects to large cables passing beneath the insulated handle, facilitating accurate ohm meter connections.

At room temperature, the resistance measures approximately 20 ohms. The winding element is safeguarded with a special varnish, yet caution is required due to the wire's fine nature.
