Resistance Box 50 Ohms

Resistance Box 50 Ohms | Precision Resistance Measurement Instrument

The Resistance Box 50 Ohms by ELMO Agencies is a precision laboratory instrument designed to provide accurate and reliable resistance values for electrical and physics experiments. Built with high-quality materials and precision-engineered resistance coils, it is widely used in schools, colleges, engineering laboratories, research centres, and technical institutions.

Precision Construction

The Resistance Box 50 Ohms is manufactured using heavy-duty rectangular brass blocks approximately 12 mm × 10 mm in size. These solid brass blocks ensure excellent electrical conductivity, mechanical strength, and long-lasting performance.

The resistance coils are carefully wound using non-inductive, double-covered Eureka or Constantan wire on insulated bakelite spools. This precision winding minimizes inductive effects and ensures stable resistance values throughout laboratory use.

The complete assembly is enclosed in a durable wooden box that protects the internal components while providing easy handling and long service life.

High Accuracy Performance

The Resistance Box is designed to deliver dependable and highly accurate resistance measurements for laboratory experiments.

Constantan Coil Accuracy

The Constantan resistance coils provide an accuracy of ±0.05% to ±0.1%, ensuring reliable and consistent resistance values for routine laboratory work.

Manganin Coil Accuracy

For applications requiring greater precision, the Manganin resistance coils offer an even higher level of accuracy ranging from ±0.02% to ±0.05%. Due to its low temperature coefficient, Manganin wire maintains stable resistance even under varying environmental conditions.
