The Kiwi Kibble Balance | Measurement Standards Laboratory NZ

October 18, 2018 Office

The Kibble balance is an apparatus that will be used to realise the kilogram after its redefinition in May 2019 based on a fundamental constant – the Planck constant. It compares the gravitational force on […]

Worth the Weight: New International Guidelines Published for Manufacturing Load Cells | NIST

April 16, 2018 Office

At the heart of every electronic weighing instrument is a device called a load cell, which takes a mechanical force and turns it into an electronic signal. Anytime something needs to be weighed in commerce […]

Using Robotic Comparators in Mass Calibration

May 16, 2016 Office

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 […]

NIST’s Million-Pound Weight Stack Restoration is Complete

April 25, 2016 Office

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 […]

Pushing the Boundaries of Traceable Measurement

May 26, 2015 Office

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 […]
