by Mettler Toledo Calibrating a weight of unknown mass requires comparison to a known reference. It’s not as simple as it sounds, however, particularly when manufacturing weights or establishing metrology standards. During manual calibration, everything […]
It’s official: NIST’s 4.45-million newton (equivalent to one million pounds-force) deadweight machine – the largest in the world – is back in one piece after a colossal 16-month effort to overhaul the system for the […]
by Mettler-Toledo In recent years, National Metrology Institutes (NMIs) around the world have fielded increasingly frequent requests for a traceable weighing standard for weights in the sub-milligram range. New weight designs springing from combined public […]
By Patrick J. Abbott & Zeina J. Jabbour Mass metrology carried out in atmospheric pressure air is suitable for most every critical application. However, mass metrology in vacuum is important in several current research projects. […]
Corporation announces the Valor™ 5000 line of standard (6,000d) and high resolution (30,000d) compact bench scales clearly and quickly display results within two seconds. A large, backlit LCD display with multiple weight units provides efficient […]
By Mike Stears Like many calibration laboratories, our laboratory provides calibrations for a wide range of instrumentation. For the most part, we calibrate the instrumentation to the manufacturer’s published specifications. As one of our services, […]
In a vault beneath a 17th-century pavilion on the outskirts of Paris sits a platinum cylinder known as Le Grand K. Since 1889 it has been the international prototype for the kilogram, the standard against […]
