Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, partly as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independent method, it can be used to check the most accurate pressure gauges, for which PTB is known as the world leader.
