PENCIL JOCKEY
Product Description
A Pencil Jockey is a small laboratory tool designed to securely hold and manipulate pencils or fine writing instruments during detailed drawing, drafting, or note-taking tasks. Commonly used in scientific laboratories, drafting rooms, and educational settings, it ensures precision and comfort during use. Typically made from lightweight, durable materials, the pencil jockey facilitates steady control and prevents slippage, especially when working with fine sketches, annotations, or measurements.
Whetstone bridge with pencil jockey
Product Description
The Whetstone Bridge with Pencil Jockey is a precision electrical instrument used to measure unknown electrical resistances by balancing two legs of a bridge circuit. It consists of a robust base, a wire or slide wire of known resistance, and a movable contact known as the pencil jockey to slide along the wire for accurate balancing. This apparatus is widely used in physics and electrical engineering laboratories for teaching and research purposes, helping students and technicians to understand the principles of Wheatstone bridge circuits and precise resistance measurements.
