World Metrology Day commemorates the signing of the Meter Convention on May 20, 1875. In recent years, it has become a day in which metrologists celebrate their quiet, largely unseen, but influential achievements to provide a measurement system that creates manufacturing interoperability, allows for precise navigation, and promotes fair trade.

Metrology is the science of measurement, and it was the need to improve measurement that caused John M. Fluke Senior to found his company. The theme for World Metrology Day 2011 is “Chemical measurements, for our life, our future.” While most of Fluke Corporation’s products are associated with electrical and electronic measurements, we also make both quiet and sometimes significant contributions to chemical measurements.

Fluke contributes to improving chemical measurements with our process calibration tools that are used to control systems that monitor and limit factory emissions, allowing them to adhere to EPA standards driving reduction in acid rain and pollutants. Fluke’s thermal imagers are used to monitor temperature in petroleum and petrochemical processing. The former Ruska Instruments, now part of Fluke Calibration, builds special custom quartz products used as heating elements in measurement equipment for the analytic chemistry industry. Fluke Calibration also produces molblox/molbox™ gas flow measurement standards, which allow chemicals in gaseous form to be distributed precisely during semiconductor manufacturing.

Fluke’s most significant contribution toward chemical measurements this year, and arguably ever, is the design and development of the PG9607 pressure standard. This instrument was part of a special experiment conducted by a team of National Measurement Institutes to re-define the Boltzmann constant, which is the physical constant relating energy at the individual particle level with temperature observed at the collective level. This fundamental physical constant is important to both chemical and physical measurements and is used by scientists worldwide. This successful experiment would not have been possible without the five-fold improvement in pressure measurement accuracy that Fluke Calibration was able to deliver.
