The world’s measurement system will be based on updated values for four fundamental constants of nature. A revised SI ( the International System of Units ) based fully on accurate values of these ...

Measurement system analysis (MSA) is an essential discipline that underpins the accuracy and reliability of data in quality control and manufacturing processes. By quantifying measurement variability, ...

Every application of measurement, including those not yet invented, can be put into one of three categories or some combination of them: monitoring of processes and operations; control of processes ...

Sensor-arm extensometers are used for performing compression, tensile, cyclic, and flexure tests. It is feasible to infinitely adjust the gage length to be suitable to the specimen to be tested.

As agreed upon by scientists and representatives from around 60 countries last year, the world's measuring systems are shifting away from using physical standards. Among the most prominent of these is ...

Particle measurements in ultra-pure water (UPW) systems can take a long time to return to a stable baseline after normal operations are interrupted by an event such as maintenance shutdowns. A ...

Measurement of signals close to the your measuring instrument’s noise floor is always difficult. For many years the best Op Amps have had input noise floors of right around 1 nV/√Hz. This makes any ...

In prehistoric times, not much needed to be measured. You ate what you found and lived where you could. The advent of agriculture and civilization, however, necessitated a way for people to measure ...
