A New Micro-Balance and Its Use (Classic Reprint) - Softcover

Inhaltsangabe

A detailed look at a micro-balance and how it achieves extreme precision in weighing tiny masses.

This edition explores a silica-fiber design that enables measurements in varied environments.

This book traces the evolution of micro-balances, from early lever and elastic balances to a modern silica-fiber instrument. It explains how a balance suspended by glass and silica fibers can operate inside a vacuum or under air, and how reading methods and case design affect accuracy. The text also describes experiments, including heating a gold sample inside a balance to observe weight changes, and discusses the practical limits of sensitivity and the factors that influence it.

Readers will gain an overview of the key concepts, techniques, and experimental setups used to push the limits of precision weighing. The material highlights how material choices, geometry, and environmental control shape performance and reliability in precision instruments.

• Overview of historical micro-balances and how they improved measurement accuracy.
• Introduction to a silica-fiber micro-balance and its advantages over knife-edge designs.
• Discussion of aerostatic compensation, vacuum environments, and magnetic arrest systems.
• Illustrative experiments, including weight changes of heated samples and related measurements.

Ideal for readers interested in precision measurement, experimental physics, and the development of weighing instruments.
