PTB-News 2.2020 So far, no internationally standardized measurement procedures have been available to measure magnetic field distributions that vary spatially on the nanometer scale. The NanoMag EMPIR metrology research project, which was spearheaded by PTB […]
The accurate measurement of radioactivity is essential for applications of ionizing radiation such as medical imaging, cancer therapy and environmental protection. To ensure that such measurements are harmonized world-wide, the BIPM operates a set of […]
by Joseph P. Fuehne, Ph.D., P.E. The Purdue Polytechnic Institute in Columbus utilizes metrology tools with targeted measurement artifacts, which may be 3-D printed or machined, to facilitate learning and provide opportunities to demonstrate competency […]
by Henry Zumbrun One might read the headline and think why is mV/V or a calibration curve relevant to me or my instrumentation? If you use load cells or other instrumentation that are calibrated using […]
Introduction Part 1 of this white paper discussed the functions and features of these high-performance instruments. The purpose of this section is to guide the hipot tester user through the steps needed to make sure […]
Introduction Electrical safety testers – often referred to as “hipot” testers – are an integral part of electrical and electronic equipment manufacturing. Hipot testers get their name from the high-potential (high voltage) they produce to […]
From fundamental physics related to Einstein’s special theory of relativity to fundamentals of metrological applications in the range of thousandths of micrometers (i.e. nanometers) – the bandwidth of this year’s Helmholtz Prize is considerable. The […]
The ControlPak is a compressed gas volume controller that can really take a beating. It provides precise control over compressed gas sources for smooth and quick calibration testing. Encased in durable, tactical plastic designed to […]
