Single Tube Laboratory Rheostat

The Single Tube Laboratory Rheostat with Sliding Contact is engineered to deliver precision and versatility in laboratory and educational environments. A layer of oxidized resistance wire is carefully wound on a porcelain tube, supported by robust end fittings to ensure stability and long service life. The sliding contact mechanism allows smooth adjustment of resistance, while three 4 mm socket terminals provide flexible connectivity for use as either a rheostat or a potentiometer.

Available in multiple models with resistance values ranging from 10 Ω to 28 Ω and current ratings up to 4.2 A, this rheostat supports a wide range of circuit applications. Its design makes it ideal for teaching laboratories, research centers, and industrial training facilities where accuracy and repeatability are critical. The porcelain tube construction ensures heat resistance and mechanical strength, while the precision winding guarantees consistent electrical performance.

By combining durability, usability, and compliance with laboratory standards, the Single Tube Laboratory Rheostat with Sliding Contact offers procurement buyers a reliable solution for electronic experiments and training programs. Institutions benefit from reduced replacement costs, enhanced teaching efficiency, and dependable performance across diverse applications.
