Knowledge of instrumentation is critical in light of the highly sensitive and precise requirements of modern processes and systems. Rapid development in instrumentation technology coupled with the adoption of new standards makes a firm, up-to-date foundation of knowledge more important than ever in most science and engineering fields. Understanding this, Robert B. Northrop produced the best-selling Introduction to Instrumentation and Measurements in 1997. The second edition continues to provide in-depth coverage of a wide array of modern instrumentation and measurement topics, updated to reflect advances in the field.
