Tungsten Carbide Bimetallic Strip, 10-Pack Subcategory_Acids and Bases Sixteen-SWG bare constantan wire on

Sixteen-SWG bare constantan wire on a 125g reel — a copper-nickel alloy with a low temperature coefficient that holds resistance steady across a wide temperature range

and a 3mm thickness

and edge-polished

5-inch mounting rod giving 5 inches total length for standard optical-bench setups

letting students read low-cell voltages and high-tension supply outputs on the same meter
