Adjustable 0-99999.9 Ohm Decade Resistor Box for Experimental Teaching Equipment

Explore the precision and versatility of our adjustable variable resistance box, an essential tool for physical and electrical experiments. This resistance box offers a measurement range from 0 to 999999 Ω, making it ideal for educational settings. Its robust plastic construction and compact dimensions (16.5*12.5*6.4cm) ensure durability and ease of use.

Perfect for demonstrating Ohm's law, it serves as an additional resistor to expand voltmeter and ammeter ranges and enables accurate measurement of unknown resistances. It also assists in gauging electromotive force and internal resistance of power supplies.

Designed with a sealed structure using a metal sheet and aluminum alloy frame, the resistance box provides stable resistance values through a precision band switch system. The low-value resistance is crafted with high-stability copper wire, while high-value resistance comes from precision metal film resistors, ensuring long-lasting accuracy.
